4. Introduction
This memo defines a portion of the Management Information Base (MIB)
for use with network management protocols in the Internet community.
In particular, it describes managed objects for Multiprotocol Label
Switching (MPLS) based fast rerouting. This MIB should be used in
conjunction with [3] and [4].
5. Brief Description of MIB Objects.
The objects described in this section support the detour
functionality described in Section 3 of [5]. Bypass tunnels are for
further study.
5.1. mplsFrrConstTable
This table contains fast-reroute constraints such as setup and
holding priorities and bandwidth for a tunnel instance to be
protected by using detour LSPs.
This table is used at the ingress node of the protected tunnel
instance to configure detour LSP setup constraints.
5.2. mplsFrrPLRTable
The mplsFrrPLRTable is an optional table that contains lists of PLRs
that initiated detour LSPs to protect tunnel instances.
When detour LSPs initiated by different PLRs to protect the same
tunnel instance, are merged together before entering an LSR then at
this LSR, entries of those PLRs point to the same detour LSP entry in
the mplsFrrDetourTable.
IETF MPLS WG Expires May 2003 [Page 2]
Internet Draft MPLS-FRR MIB November 1, 2002
5.3. mplsFrrDetourTable
The mplsFrrDetourTable shows the detour LSPs in each node (ingress,
transit and egress LSRs). An entry of this table represents a detour
LSP. Each detour is identified by:
- tunnel index (which is set to the tunnel-id of the LSP protected
by this detour),
- tunnel instance (which is set to the LSP-id of the LSP protected
by this detour),
- ingress node (which is set to the ingress node of the LSP
protected by this detour),
- egress node (which is set to the egress node of the LSP
protected by this detour), and
- detour index.
Multiple detours of the same protected LSP may go through the same
node. In this case, the first four identifiers are not sufficient to
uniquely identify each detour LSP. Therefore, an additional detour
index is introduced.
Each entry describes the properties of the detour LSP like bandwidth,
setup and holding priority,... and also whether or not the detour LSP
is merged with another detour LSP or with the protected LSP.
mplsFrrDetourTable does not define the in and out segments forming
the detour. Instead, these are defined by creating rows in the in-
segment and out-segment tables, defining relationships in the cross-
connect table and referring to these rows in the mplsFrrDetourTable
using a cross-connect row pointer (mplsFrrDetourXCPointer). These
segment and cross-connect related objects are defined in [4].
When detour LSPs are merged, then for each individual detour LSP, an
entry is created in this table. Each such detour LSP points to a
different cross-connect entry. These cross-connect entries have the
same mplsXCIndex and mplsOutSegmentIndex. mplsOutSegmentIndex will
point to the entry of the out segment table created for the final
detour LSP selected as a result of the merging rules. This final
detour LSP is given by mplsFrrDetourMergedDetourIndex object in each
entry of the merged detour LSPs. In case detour LSPs are merged with
the protected LSP, mplsOutSegmentIndex will point to the entry of the
out segment table created for the protected LSP. In this case the
mplsFrrDetourMergedDetourIndex object is not relevant.
This table is optional and is only required in case mplsFrrPLRTable
is supported.
ED NOTE: Need to add description of Facility-based FRR tables
and explanation of new MIB structure.
