3. 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].
4. 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.
4.1. mplsFrrConstraintTable
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.
4.2. mplsFrrDetourPathTable
The mplsFrrDetourPathTable is used to show the paths of all detours
established in the network for a particular tunnel instance for
which fast-reroute is requested.
Every detour path is uniquely identified by a path index. An entry
represents 1 hop of a detour path (identified by a hop index),
therefore there are as many entries for a particular detour as there
are hops in that particular detour path.
This table is read-only and is only applicable at the ingress LSR
that initiated the protected tunnel instance. There may be several
tunnels established with fast-reroute at the same ingress LSR. In
this case, all detour paths of each individual such tunnel instances
appear in this table. Therefore, in addition to the path and hop
index, a tunnel Id and tunnel instance, which identify uniquely a
certain LSP, are defined as part of the index. Note that for the
tunnel instance, the LSP-ID is used.
This table requires the support of the Backup Record Route Object
(BRRO). Therefore this table is optional and only required when BRRO
is supported.

The following illustrates an example of the
mplsFrrDetourPathTable:
Network topology
A======B======C
| | |
| | |
D------E------F
Protected LSP (LSP-1 of Tunnel-1) is established through nodes
A-B-C.
Node A calculates path A-D-E-F-C for the detour.
Node B calculates path B-E-F-C for the detour.
Detour of node A and node B are merged together at node E and
detour of A is selected as the final detour.
The following shows the content of the mplsFrrDetourPathTable
at the ingress node A.
DetourPathIndex value 1 is assigned to the detour of A.
DetourPathIndex value 2 is assigned to the detour of B.

4.3. mplsFrrDetourTable
The mplsFrrDetourTable is an optional table that 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:
- detour tunnel index (which is set to the tunnel-id of the LSP
protected by this detour),
- 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 LSPs point 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.
4.4. mplsFrrPLRTable
The mplsFrrPLRTable contains the originating nodes together with the
avoid nodes of all detour LSPs merged with each other.
This table is optional and is only required in case
mplsFrrDetourTable is supported.
Cetin, et. al. [Page 4]
draft-cetin-mpls-fastreroute-mib-00.txt February 2002
4.5. mplsFrrHopTable
The mplsFrrHopTable contains the list of hops for explicit path
(e.g., the content of the ERO of RSVP) and record path (e.g., the
content of the RRO of RSVP) of a detour LSP. Each detour has two
different sets of hops in this table: a set for the explicit path
hops and another set for the record path hops, pointed by
mplsFrrDetourExplicitPathIndex and the mplsFrrDetourRecordPathIndex,
respectively, from the mplsFrrDetourTable.
This table is optional and is only required in case
mplsFrrDetourTable is supported.
4.6. mplsFrrInSegTable
The mplsFrrInSegTable contains a description of the incoming MPLS
segment for a particular detour LSP and their associated parameters.
The table also includes objects to measure the performance.
This table is optional and not required when LSR-MIB [4] is
supported or mplsFrrDetourTable is not supported.
4.7. mplsFrrOutSegTable
The mplsFrrOutSegTable contains a description of the outgoing MPLS
segment for a particular detour LSP and their associated parameters.
The table also includes objects to measure the performance.
This table is optional and not required when LSR-MIB [4] is
supported or mplsFrrDetourTable is not supported.
