# Monitoring MLD on Mapped Outgoing Interfaces

#### Purpose

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

#### Action

To display the current mappings to all mapped outgoing interfaces:

    host1# show ipv6 mld mapped-oif

          OIF       Oper  Group Address  Source Address     Join I/F      Map Name
    --------------- ---- --------------- --------------- --------------- ----------
    ATM5/0.120      Up   ff3e::2         10::10          ATM5/0.12       OIFMAP
                                                         ATM5/0.13       OIFMAP
    ATM5/0.121      Up   ff3e::1         *               ATM5/0.12       OIFMAP
                                                         ATM5/0.13       OIFMAP
                         ff3e::2         10::11          ATM5/0.12       OIFMAP
                                                         ATM5/0.13       OIFMAP
