Bidir-PIM Configuration on 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
are learned correctly.
