A Dedicated Routing Policy Specification Language Interface Identifier
for Operational Testing
Abstract
The deployment of new IP connectivity typically results in
intermittent reachability for numerous reasons that are outside the
scope of this document. In order to aid in the debugging of these
persistent problems, this document proposes the creation of a new
Routing Policy Specification Language attribute that allows a network
to advertise an IP address that is reachable and can be used as a
target for diagnostic tests (e.g., pings).

1. Introduction
The deployment of new IP connectivity typically results in
intermittent reachability for numerous reasons that are outside the
scope of this document. In order to aid in the debugging of these
persistent problems, this document proposes the creation of a new
Routing Policy Specification Language attribute [RFC4012] that allows
a network to advertise an IP address that is reachable and can be
used as a target for diagnostic tests (e.g., pings).
The goal of this diagnostic address is to provide operators a means
to advertise selected hosts that can be targets of tests for such
common issues as reachability and Path MTU discovery.
The capitalized key words "MUST", "MUST NOT", "REQUIRED", "SHALL",
"SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and
"OPTIONAL" in this document are to be interpreted as described in
[RFC2119].
2. RPSL Extension for Diagnostic Address
Network operators wishing to provide a diagnostic address for their
peers, customers, etc., MAY advertise its existence via the Routing
Policy Specification Language [RFC4012] [RFC2622]. The pingable
attribute is a member of the route and route6 objects in the RPSL.
The definition of the pingable attribute is shown in Figure 1.
+-----------+-------------------+--------------+
| Attribute | Value | Type |
+-----------+-------------------+--------------+
| pingable | <ipv6-address> or | optional, |
| | <ipv4-address> | multi-valued |
+-----------+-------------------+--------------+
| ping-hdl | <nic-handle> | optional, |
| | | multi-valued |
+-----------+-------------------+--------------+

RFC 5943 RPSL Pingable Attribute August 2010
The exact definitions of <ipv4-address> and <nic-handle> can be found
in [RFC2622], while the definition of <ipv6-address> is in [RFC4012].
The pingable attribute allows a network operator to advertise an IP
address of a node that should be reachable from outside networks.
This node can be used as a destination address for diagnostic tests.
