Abstract
Operating the global routing ecosystem entails a diverse set of
interacting components, while operational practice evolved over time.
In that time, terms emerged, disappeared, and sometimes changed their
meaning.
To aid operators and implementers in reading contemporary drafts,
this document provides an overview of terms and abbreviations used in
the global routing operations community. The document explicitly
does not serve as an authoritative source of correct terminology, but
instead strives to provide an overview of practice.

4. Used Terminology by Topic
This section describes terms used in the context of global routing
operations, grouped by topic. Terms may have a different meaning
depending on the context in which they are used. Hence, terms may
appear in multiple subsections with different descriptions.
4.1. General Terms
This section describes general terms used in the context of global
routing operations, regardless of context.
Autonomous System:
A connected group of one or more IP prefixes run by one or more
network operators which has a SINGLE and CLEARLY DEFINED routing
policy.
Autonomous System Number:
A 32-bit number uniquely identifying an Autonomous System.
AS Confederation Identifier:
is according to [RFC5065] an externally visible autonomous system
number that identifies a BGP confederation as a whole.
Fiebig & Tremmel Expires 5 April 2027 [Page 5]
Internet-Draft BGP TERMS October 2026
Bidirectional Forwarding Detection:
BFD is a protocol used by BGP to check if a configured neighbor is
reachable. Packets are sent rapidly between two systems (rapidly
means in the 100ms time range). If no packets are received from
the neighbor for a given time, the neighbor is considered to be no
longer reachable. This lack of reachability is then signaled to
other protocols like BGP. BFD is defined in [RFC5880]. Its
application for IPv4 and IPv6 is defined in [RFC5881]. [RFC5882]
is about the general application of BFD and [RFC5883] describes
BFD on multihop paths.
BGP:
Border Gateway Protocol, Version 4 [RFC4271]. BGP is the routing
protocol used for Internet (IPv4 and IPv6) routing. It is also
used by many other applications.
BGP Path Attribute:
BGP update messages for prefixes contain not only the AS-Path but
also other attributes. BGP Path Attributes fall into four
different categories: well-known mandatory, well-known
discretionary, optional transitive, optional non-transitive.
Well-known mandatory BGP Path Attribute:
A BGP Path Attribute that needs to be understood by all BGP
implementations and must be included in all BGP routes.
Well-known discretionary BGP Path Attribute:
A BGP Path Attribute that needs to be understood by all BGP
implementations but is not required to be included in BGP routes.
Optional transitive BGP Path Attribute:
Optional transitive BGP Path Attributes are conditionally carried
in BGP routes based on their defining feature. Implementations
that do not understand an optional transitive Path Attribute are
expected to propagate the attribute to their neighbors.
Optional non-transitive BGP Path Attribute:
Optional non-transitive BGP Path Attributes are conditionally
carried in BGP routes based on their defining feature.
Implementations that do not understand an optional non-transitive
Path Attribute will discard them and they are not propagated to
their neighbors as a result.
Enhanced Interior Gateway Routing Protocol:
EIGRP is an IGP defined by Cisco in the 1980s to distribute
routing information within a network. It was later openly
specified in [RFC7868].
Fiebig & Tremmel Expires 5 April 2027 [Page 6]
Internet-Draft BGP TERMS October 2026
Exterior Gateway Protocol:
EGP was a predecessor to BGP. First defined in 1982 in [RFC827],
it became obsolete once BGP was widely used (around 1994).
Additionally, as a general term, it is used for protocols used to
exchange routing information between ASes. In that meaning, BGP
is currently the only EGP.
Interior Gateway Protocol:
An IGP is a protocol running inside an Autonomous System. It is
typically used to distribute the IP addresses of router
interfaces.
IS-IS:
The Intermediate System to Intermediate System protocol is an IGP
running directly on top of layer 2. It is typically used to
distribute interface addresses within a network. IS-IS was
originally defined by OSI in ISO DP 10589. It was later published
in the IETF in [RFC1195].
Local Internet Registry:
An LIR is an organization/company which receives IP address
resources or Autonomous System Numbers as an allocation from a
Regional Internet Registry and assigns these resources to end
users.
Open Shortest Path First:
OSPF is a link state routing protocol. It is used as an IGP. It
was first specified in [RFC2328].
Regional Internet Registry:
An RIR is an entity responsible for allocating IP addresses and AS
numbers to NIRs and LIRs. There are currently five RIRs: Afrinic,
APNIC, ARIN, LACNIC, and RIPE NCC. Each is responsible for a
different region.
Routing Information Protocol:
RIP is an old and by now obsolete protocol which was used to
distribute routing information. RIP is no longer in use. It was
originally defined in [RFC1058].
RIPE:
RIPE is shorthand for Réseaux IP Européens, which is the community
of network operators in the RIPE NCC's service region. See also
RIPE NCC.
Fiebig & Tremmel Expires 5 April 2027 [Page 7]
Internet-Draft BGP TERMS October 2026
RIPE NCC:
The RIPE NCC, sometimes also just called the NCC, is the RIR for
75 countries spanning Europe, parts of central Asia, and the
Middle East.
Operator:
Individual, group of people, or organizational unit responsible
for operating BGP speakers, i.e., making administrative changes,
as well as defining and setting policies for all BGP speakers
within an organization.
Router:
In this document, router always refers to a BGP speaker.
Customer Edge (CE) Router:
Router at the customer's premises, may be connected to PE routers.
Cone:
The set of ASes who are either direct downstreams of an AS, or in
the cone of any of those ASes. Depending on the context this also
includes the joint set of prefixes that may be originated by ASes
in a cone.
Global Routing Table:
The set of all routes for an address family that have been
received from external BGP Neighbors.
Route Selection:
The process when a BGP speaker applies the locally configured
policy to select the best route from multiple available options
according to that policy. See "Decision Process" in [RFC4271].
Network Layer Reachability Information:
General description for network destinations. Often called
"prefixes".
Default Free Zone:
Part of the Internet where routers do not carry default routes.
Round Trip Time:
The Round Trip Time between two hosts is the time measured
(typically in seconds or milliseconds) that it takes from sending
out a packet until receiving a reply.
TCP:
The Transmission Control Protocol is part of the TCP/IP protocol
stack. It is a connection oriented protocol taking care that
everything which is sent is also received.
Fiebig & Tremmel Expires 5 April 2027 [Page 8]
Internet-Draft BGP TERMS October 2026
TCP-AO:
The Transmission Control Protocol Authentication Option [RFC5925]
is used to provide authentication and integrity for BGP.
TCP-MD5:
MD5 is a hashing algorithm, used to generate a checksum over given
data. In the context of BGP, it typically refers to the obsolete
TCP-MD5 feature [RFC2385]. It has been replaced by TCP-AO.
Time To Live:
The TTL is a counter in the IPv4 header which is decreased every
time a packet is forwarded by a router. If this counter hits
zero, the packet is discarded and an ICMP Time Exceeded message is
sent back to the originator of the packet. It was replaced by the
Hop Limit field in IPv6.
4.2. Neighbor Relation Terms
This section lists terms used to describe relationships between
different ASes.
AS Confederation:
According to [RFC5065] a collection of autonomous systems
represented and advertised as a single AS number to BGP speakers
that are not members of the local BGP confederation.
ICMP:
Internet Control Message Protocol - this protocol is used to
signal errors when forwarding packets.
Cone:
The set of ASes who are either direct downstreams of an AS, or in
the cone of any of those ASes. Depending on the context this also
includes the joint set of prefixes that may be originated by ASes
in a cone.
Network edge:
Last routers under the control of an operator connected to routers
of other networks.
Mutual Transit:
When two directly connected ASes both advertise a full BGP table
to each other. (See: [I-D.ietf-sidrops-aspa-verification])
Fiebig & Tremmel Expires 5 April 2027 [Page 9]
Internet-Draft BGP TERMS October 2026
Upstream Provider / Transit Provider:
In a direct relationship between two ASes the one announcing
either the full BGP routing table to the other or allowing the
other to point a default route to itself. (See: [RFC9234], also
known as the provider in a customer-provider relationship.)
Downstream Customer:
In a direct relationship between two ASes the one receiving a full
BGP table from the other or pointing a default route to the other.
(See: [RFC9234], also known as the customer in a customer-provider
relationship.)
Peer:
Two directly connected ASes who only advertise routes they
originate or learned from their downstreams to each other. (See:
[RFC9234])
Providing Transit:
Forwarding packets destined for addresses in an advertised prefix,
while advertising a full BGP table or default route to the
neighbor.
Providing Upstream:
See: Providing Transit
Provider (P) Router:
A router within the core of a provider's network, usually implying
the use of MPLS within the provider's network. Connected to other
P and PE routers.
Provider Edge (PE) Router:
Like Network Edge, usually implying the use of MPLS within the
provider's network. Connected to other PE, P, and CE routers.
Depeering:
Removing sessions with a neighboring AS.
Neighbor:
An AS to which an established BGP session exists.
4.3. Routing Terms
This section describes terms specific to technical aspects of
routing.
BGP Speaker:
A device exchanging routes with other BGP speakers using the BGP
protocol.
Fiebig & Tremmel Expires 5 April 2027 [Page 10]
Internet-Draft BGP TERMS October 2026
Full Table:
A routing table containing a route to all prefixes in the GRT but
not the default route.
Exporting a Prefix:
Advertising a prefix to a neighbor.
Importing a Prefix:
Accepting a prefix advertised by a neighbor and considering it for
route selection and import into the local AS' routing table.
Network edge:
Last routers under the control of an operator.
Originating a Prefix:
Announcing a prefix with only your AS in the AS-Path.
Propagating a Prefix:
Advertising a prefix you have received from another AS and adding
your AS to the AS_PATH before announcing the prefix to further
neighboring ASes.
BGP Neighbor:
Also just 'Neighbor'. Two BGP speakers that exchange NLRI using
the BGP protocol are neighbors.
Peer:
A BGP neighbor, if not used to describe the peering relationship.
Prepending:
Adding one or more instances of an AS number to the left-hand side
of the AS_PATH, typically to influence route selection.
Traffic Engineering:
Making changes to properties of imported and exported NLRI to
influence route selection, and thereby the flow of traffic.
Converging:
Used to describe the process of a BGP speaker learning and
evaluating all routes from its neighbors, and finding the
preferred route for each destination. Reconverging is often also
used to describe an ongoing selection process reevaluating all
routes sent by neighbors, e.g., after a loss of connectivity to
one or multiple neighbors.
Fiebig & Tremmel Expires 5 April 2027 [Page 11]
Internet-Draft BGP TERMS October 2026
Route Reflector:
A Route Reflector is an iBGP speaker which sends all prefixes it
receives out to its Route Reflector Clients. It is a central
component for network designs that do not use a full mesh for iBGP
speakers.
Route Reflector Client:
A Route Reflector CLient is an iBGP speaking node with usually
only one iBGP connection to a Route Reflector.
Default Route:
The default route is a route which covers every destination for
which there is no specific route in the routing table. The
destination of the default-route is often called the default
destination or the gateway of last resort.
Blackholing:
As a general term, blackholing refers to packets silently being
dropped, i.e., without the sender being notified via an ICMP or
ICMP6 message. For the additional meaning in the context of
network security, please see below.
Multi Exit Discriminator:
MED is a metric in BGP which is used to signal neighboring ASes
with multiple entry points to the network which inbound traffic
path for a prefix is preferred.
Local Preference:
The local preference is the first evaluated BGP Attribute in the
best path selection process when comparing multiple NLRI for the
same prefix. It is an integer value, and NLRI with a higher local
preference will be preferred. It is redistributed via iBGP inside
an Autonomous System}
MPLS:
Multiprotocol Label Switching is a procedure to make routing
decisions faster. When a packet enters a network it will get a
label attached signaling which route it should take to its
destination and which priority it has.
L2VPN:
A Layer 2 Virtual Private Network connects two physically distant
networks in a way that makes them appear to be one. Packets
between hosts in those 2 connected networks can communicate as if
on the same layer 2 network via switching.
Fiebig & Tremmel Expires 5 April 2027 [Page 12]
Internet-Draft BGP TERMS October 2026
Router:
Generally a term for a system forwarding network traffic on Layer
3. In the context of BGP, this usually refers to a BGP speaker.
4.4. Security Terms
This section describes terms used in the context of routing security.
Route Flapping:
A route that is constantly announced and withdrawn or otherwise
sees constant change.
BGP Hijack / Route Hijack:
A route hijack occurs when an AS announces a route that it is not
authorized to announce, causing traffic to be diverted from its
intended route or destination. A route hijack may result from
either accidental misconfiguration or malicious action.
Route Leak:
The propagation of one or more routing announcements beyond their
intended scope, in violation of intended routing policies. Route
leaks may be accidental or malicious. (See [RFC7908].)
Update Storm:
A continuous high volume stream of BGP Updates sent to one or
multiple neighbors.
Cascading Update Storm:
When an update storm traverses beyond directly connected
neighbors.
Blackholing:
Announcing prefixes grouped by a specific community to inform all
neighbors observing the announcement that traffic to the
destination should be dropped.
ROA:
Route Origin Authorization - a cryptographically signed object in
the RPKI through which an IP address block holder authorizes an
Autonomous System to originate routes to one or more prefixes. A
prefix entry may optionally specify a maximum prefix length. (See
[RFC9582].)
RPKI:
Resource Public Key Infrastructure represents the allocation
hierarchy of IP address space and Autonomous System numbers and
supports cryptographically verifiable statements about Internet
number resources and their use. (See [RFC6480].)
Fiebig & Tremmel Expires 5 April 2027 [Page 13]
Internet-Draft BGP TERMS October 2026
RPKI validator:
An RPKI validator is a piece of software that fetches RPKI
certificates and ROAs from RPKI publication points, checks the
signatures of the certificates and ROAs.
RPKI-RTR Protocol:
The RPKI to Router Protocol is used to communicate a validator's
view on the RPKI to routers, providing and maintaining a list of
certified prefixes and their allowed originating AS numbers. RTR
may be an independent daemon, or can also be integrated in an RPKI
validator.
DDOS:
A distributed denial of service (DDOS) attack is an attack against
a system via the Internet. The attacker uses multiple (sometimes
millions of) network sources to send more traffic towards the
attacked system than it can handle. Collateral damage is quite
often the network infrastructure to which the attacked system is
connected to.
5. IANA Considerations
This document does not require any IANA actions.
6. Security Considerations
This document describes currently used terminology and does not make
recommendations. As such, it does not have security considerations.
