pimStarGRPFRoutePrefixLength
Module: PIM-STD-MIB
OID (symbolic): PIM-STD-MIB::pimStarGRPFRoutePrefixLength
OID (numeric): 1.3.6.1.2.1.157.1.4.1.18
Node type: OBJECT-TYPE
Type: InetAddressPrefixLength
Access: read-only
Description:
The prefix length that, when combined with the corresponding value of pimStarGRPFRouteAddress, identifies the route used to find the RPF interface towards the RP. The InetAddressType is given by the pimStarGRPFNextHopType object.
What is pimStarGRPFRoutePrefixLength?
This read-only object specifies the network prefix length (in bits) of the routing table entry used to determine the reverse-path forwarding (RPF) interface toward the Rendezvous Point (RP) for multicast group traffic. Combined with the corresponding pimStarGRPFRouteAddress, it identifies the exact unicast route the router uses to validate incoming multicast packets from a group. Multicast routers query this to verify their RPF calculations and troubleshoot multicast forwarding issues.
