Clear commands for IGMP snooping
18
To display PIM SM snooping information for a specific (source, group) pair, enter a command such
as the following at any level of the CLI.
Syntax: show ip multicast pimsm-snooping <group-address> [<source-ip-address>]
The device determines which address is the group address and which one is the source address
based on the ranges that the address fall into. If the address is within the range of source
addresses, then the router treats it as the source address. Likewise, if the address falls in the
range of group addresses, then the router assumes it is a group address.
The output shows the following information.
