GenerationId

Used by neighboring routers to detect whether a reset or disable/enable DVMRP action has occurred to the switch or to a particular interface. If so, the router should resend the entire multicast routing table to its neighbor immediately instead of waiting for the next scheduled update.
|
NumRoutes
|
The number of entries in the routing table. Use this
information to monitor the routing table size to detect illegal advertisements of multicast routes.
|
ReachableRoutes
|
The number of entries in the routing table with noninfinite metrics. Use this number to detect network partitions by observing the ratio of reachable routes to total routes.
