Purpose

Display the current mappings to all the mapped outgoing interfaces or to the specified mapped outgoing interface.

Action

To display the current mappings to all the mapped outgoing interfaces:

host1# show ip igmp mapped-oif
     OIF       Oper  Group Address  Source Address     Join I/F      Map Name
