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. 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. 4.2. 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. 4.3. 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. Cetin, et. al. [Page 2] draft-ietf-mpls-fastreroute-mib-00.txt December 2002 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. 4.4. 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 mplsFrrPLRTable is supported. 4.5. 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 mplsFrrPLRTable is not supported. 4.6. mplsFrrOutSegTable Cetin, et. al. [Page 3] draft-ietf-mpls-fastreroute-mib-00.txt December 2002 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 mplsFrrPLRTable is not supported. 5.
