MSDP-MIB

MSDP-MIB

Function Overview

RFC 4624 defines MSDP-MIB. This MIB is mainly used to manage and monitor MSDP.

Root directory:

iso(1).org(3).dod(6).internet(1).experimental(3).msdpMIB(92)

Relationships Between Tables

Figure 161-1  Relationship between msdpPeerTable, msdpSACacheTable, and msdpMeshGroupTable

Figure 161-1 shows the relationship between msdpPeerTable, msdpSACacheTable, and msdpMeshGroupTable. SA entries in msdpSACacheTable are generated on the local switch when SA messages are received from peers. Therefore, you can find the corresponding peer record in msdpPeerTable based on the msdpSACachePeerLearnedFrom and msdpSACacheRPFPeer objects in msdpSACacheTable. Similarly, mesh groups should be configured after peer relationship is set up. Therefore, msdpMeshGroupPeerAddress in msdpMeshGroupTable has a corresponding msdpPeerRemoteAddress in msdpPeerTable.
