The MPLS WG Archive[Date Prev][Date Next][Thread Prev][Thread Next] [Date Index][Thread Index][Author Index][Subject Index] Suggested improvements to the Fast Reroute MIB definition in draft-ietf-mpls-fastreroute-mib-01
Nic, I realized that there was a typo in the mplsFrrTunARHopEntry description of version 02. It is corrected (see attachment). I have also added mplsFrrTunARHopBandwidthProtect and mplsFrrTunARHopNodeProtect objects to the mplsFrrTunARHopTable. Riza.

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].
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 backup LSPs (detour LSPs or by-pass tunnels).
This table is used at the ingress node of the protected tunnel
instance to configure backup 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.
5.3. mplsFrrDetourTable
The mplsFrrDetourTable shows the detour LSPs in each node (ingress,
transit and egress nodes). An entry of this table represents a detour
LSP.
Each detour is identified by:
- tunnel index:
set to the tunnel-id of an LSP protected by a detour.
- tunnel instance: consists of two parts
1) lower 16 bits: - protected tunnel instance
- uniquely identifies a protected LSP within
a tunnel.
2) higher 16 bits: - detour instance
- uniquely identifies a detour LSP of a protected
tunnel instance.
Multiple detours of the same protected LSP may go
through the same node. In this case, higher 16 bits
of the tunnel instance object is used as a detour
instance.
- ingress node:
set to the ingress node of an LSP protected by a detour.
- egress node:
set to the egress node of an LSP protected by a detour.
A detour LSP is also considered as an instance of a protected tunnel.
Therefore, each detour LSP will have an entry in the mplsTunnelTable (defined
in the MPLS-TE-MIB).
In the mplsTunnelTable, higher 16 bits of the tunnel instance will be used
as detour instance. Note that for the protected tunnel instances, higher 16 bits
of the tunnel instance must be all zeros.
This table is optional and is only required in case mplsFrrPLRTable
is supported.
5.4. mplsFrrTunnelARHopTable
This table extends mplsTunnelARHop table (defined in the MPLS-TE MIB)
with fast-reroute objects which specifies the status of local
protection (availability and in-use) per hop traversed by a protected
tunnel.
The support of this table is optional since not all MPLS signalling
protocols may support mplsTunnelARHopTable.
ED NOTE: Need to add description of Facility-based FRR tables
and explanation of new MIB structure.

DESCRIPTION
"The mplsFrrDBTable provides information about the fast

protecting backup tunnel and protected tunnel. MPLS
interfaces defined on this node are protected by backup
tunnels and are indexed by mplsInterfaceConfIndex. Backup
tunnels defined to protect the tunnels traversing an
interface, and are indexed by mplsTunnelIndex. Note that the
tunnel instance index is not required, since it is implied
to be 0, which indicates the tunnel head interface for the
protecting tunnel. The protecting tunnel is defined to exist
on the PLR in the FRR specification. Protected tunnels are
the LSPs that traverse the protected link. These LSPs are
uniquely identified by mplsTunnelIndex, mplsTunnelInstance,
mplsTunnelIngressLSRId, and mplsTunnelEgressLSRId."
