Note The Cisco MWR 2941 does not support all of the commands described in the Cisco IOS Release 12.2SR
documentation.
Verifying a Multicast Configuration
You can use the following commands to verify your configuration.
• show hosts—Displays the default domain name, the style of name lookup service, a list of name
server hosts, and the cached list of hostnames and addresses specific to a particular Domain Name
System (DNS) view or for all configured DNS views.
• show ip igmp groups [group-name | group-address | interface-type interface-number]
[detail]—Displays the multicast groups having receivers that are directly connected to the router
and that were learned through IGMP. A receiver must be active on the network at the time that this
command is issued in order for receiver information to be present on the resulting display.
• show ip igmp ssm-mapping—Display information about Source Specific Multicast (SSM)
mapping or the sources that SSM mapping uses for a particular group.
• show ip mroute [vrf vrf-name] group-address—Displays the contents of the IP multicast routing
table.
• show ip msdp [vrf vrf-name] peer [peer-address | peer-name]—Displays detailed information
about Multicast Source Discovery Protocol (MSDP) peers.
• show ip msdp [vrf vrf-name] summary—Displays Multicast Source Discovery Protocol (MSDP)
peer status.
• show ip pim [vrf vrf-name] mdt bgp—Shows details about the Border Gateway Protocol (BGP)
advertisement of the route distinguisher (RD) for the multicast distribution tree (MDT) default
group.
• show ip pim mdt history—Displays information about the history of data multicast distribution
tree (MDT) groups that have been reused.
• show ip pim [vrf vrf-name] mdt send—To display the data multicast distribution tree (MDT)
groups in use.
• show ip pim rp [mapping] [rp-address]—Displays RPs known in the network and shows how the
router learned about each RP.
• show mls ip multicast group group-address—Displays MLS IP information.

Configuring Pseudowire
This section describes how to configure pseudowire on the Cisco MWR 2941. For an overview of
pseudowire, see “Cisco Pseudowire Emulation Edge-to-Edge” section on page 1-3.
The Cisco MWR 2941 supports pseudowire connections using SAToP, CESoPSN, and ATM over
MPLS. The following sections describe how to configure pseudowire connections on the Cisco MWR
2941.
