Preventing a PIM Router from Forming an Adjacency
To prevent a router from participating in PIM (for example, to configure stub multicast routing), use the following command.
• Prevent a router from participating in PIM.
INTERFACE mode
ip pim neighbor-filter
Preventing a Source from Registering with the RP
To prevent the PIM source DR from sending register packets to route processor (RP) for the specified multicast source and group, use
the following command. If the source DR never sends register packets to the RP, no hosts can ever discover the source and create a
shortest path tree (SPT) to it.
• Prevent a source from transmitting to a particular group.
CONFIGURATION mode
ip pim register-filter
In the following example, Source 1 and Source 2 are both transmitting packets for groups 239.0.0.1 and 239.0.0.2. R3 has a PIM register
filter that only permits packets destined for group 239.0.0.2. An entry is created for group 239.0.0.1 in the routing table, but no outgoing
