Configuration Sequence
Step 9 Exit the backhaul interface.
Router(config-if)# exit
Router(config)#
Step 10 Follow these steps to configure multicast on the Ethernet shorthaul interface.
a. Enter the Ethernet shorthaul interface.
Router(config)# interface vlan 3
Router(config-if)#
a. Use the ip pim sparse-mode command to enables PIM on the interface. You must use sparse mode.
Router(config-if)# ip pim sparse-mode
b. Use the ip pim query-interval command to configure the frequency of Protocol Independent
Multicast (PIM) query (hello) messages.
Router(config-if)# ip pim query-interval 2
c. Use the ip igmp query-max-response-time command to configure the maximum response time
advertised in Internet Group Management Protocol (IGMP) queries.
Router(config-if)# ip igmp query-max-response-time 5
d. Use the ip pim version command to configure the Protocol Independent Multicast (PIM) version of
the interface.
Router(config-if)# ip pim version 2

To verify your IP Multicast configuration, see Verifying a Multicast Configuration. For more
information about configuring Multicast, see the Cisco IOS IP Multicast Configuration Guide, Release
12.2SR.
Note The Cisco MWR 2941 does not support all of the commands described in the Cisco IOS Release 12.2SR
documentation.
Configuring Source-Specific Multicast
Source Specific Multicast (SSM) is an extension of IP multicast where datagram traffic is forwarded to
receivers from only those multicast sources that the receivers have explicitly joined. For multicast
groups configured for SSM, only source-specific multicast distribution trees (not shared trees) are
created.
Follow these steps to configure source-specific multicast (SSM).
Step 1 Enter enable mode.

Step 2 Enter configuration mode.
