Bidir-PIM Configuration on Cisco IOS XR Software: Example

An access list on the RP can be used to specify a list of groups to be advertised as bidirectional PIM
(bidir-PIM).
The following example shows how to configure an RP for both PIM-SM and the bidir-PIM mode groups.
The bidir-PIM groups are configured as 224/8 and 227/8, with the remaining multicast group range
(224/4) configured as PIM-SM.

Issue the show pim group-map command and verify the output to ensure that the configured mappings

Calculating Rates per Route: Example

The following example illustrates output from hardware counters based on rate per route for a specific
source and group address location:
RP/0/0/CPU0:router# configure

RP/0/0/CPU0:router(config-mcast-default-ipv4)# rate-per-route

RP/0/0/CPU0:router(config-mcast-default-ipv4)# accounting per-prefix
