MIB Object		Notes
• mplsTunnelResourceStorageType		Read-only. Value is readOnly(5).

The mplsTunnelTable allows new MPLS tunnels to be created between an MPLS LSR and a remote endpoint and existing tunnels to be reconfigured or removed. The Cisco 7600 supports point-to-point tunnel segments, although multi-point-to-point and point-to-multipoint connections are supported by an LSR acting as a cross-connect. Each MPLS tunnel can have one out-segment originating at an LSR and one in-segment terminating at that LSR. The mplsTunnelTable is enhanced by the mplsTunnelPerfTable which provides several counters to measure the performance of the MPLS tunnels.

The mplsTunnelResourceTable indicates the resources required for a tunnel. Multiple tunnels can share the same resources by pointing to the same entry in this table. Tunnels that do not share resources must point to separate entries in this table.

The mplsTunnelHopTable indicates strict or loose hops for an MPLS tunnel defined in mplsTunnelTable, when you establish the hop using signaling. Multiple tunnels share the same hops by pointing to the same entry in this table. Each row also has a secondary index, mplsTunnelHopIndex, corresponding to the next hop of this tunnel. The scalar mplsTunnelMaxHops indicates the maximum number of hops that you can specify on each tunnel supported by this LSR. The mplsTunnelARHopTable indicates the actual hops crossed by a tunnel as reported by the MPLS signaling protocol after the tunnel is setup.

There are three notifications in this MIB module. The notifications mplsTunnelUp and mplsTunnelDown indicate that the value of mplsTunnelOperStatus has transitioned to up(1) or down(2). The notification mplsTunnelRerouted is generated when a tunnel is rerouted or re-optimized.

MPLS-VPN-MIB

The MPLS-VPN-MIB:

•Describes managed objects for modeling a Multiprotocol Label Switching/Border Gateway Protocol Virtual Private network

•Configures and monitor routes and route targets for each VRF instance on a router

•Facilitates provisioning VPN Routing and Forwarding (VRF) instances on MPLS interfaces

•Measures the performance of MPLS/BGP VPNs

The MIB is based on Revision 05 of the IETF MPLS-VPN-MIB.

MIB Constraints

Table 3-35lists the constraints that the Cisco 7600 Series router places on objects in the

MPLS-VPN-MIB. For detailed definitions of MIB objects, see the MIB.
