Chapter 4 Configuring the Cisco MWR 2941 Router Using the CLI
Configuration Sequence
Step 3 Complete the following steps to create an access list to permit specific Multicast Groups for use with
source-specific multicast configuration.
a. Use the ip access-list command to define a standard IP access list.
Router(config)# ip access-list standard SSM
b. Use the permit to allow traffic from multicast groups. Repeat this step for each each network from
which you want to allow traffic.
Router(config)# permit 239.193.0.0 0.0.255.255
Router(config)# permit 239.194.0.0 0.0.255.255
Note For more information about using access control lists (ACLs), see Creating an IP Access List and
Applying It to an Interface.
Step 4 Use the ip multicast-routing command to enable IP multicast routing. You can use the distributed
keyword to enable Multicast Distributed Switching.
Router(config)# ip multicast-routing
Step 5 Use the ip pim ssm command to configure SSM service. You can use the following keywords.
• The default keyword defines the SSM range access list as 232/8.
• The range keyword specifies the standard IP access list number or name that defines the SSM range.
Router(config)# ip pim ssm range SSM
Step 6 Use the ip pim register-source command to configure the IP source address of a register message to an
interface address other than the outgoing interface address of the designated router (DR) leading toward
the rendezvous point (RP).
Router(config)# ip pim register-source Loopback0
Step 7 Follow these steps to configure the Ethernet backhaul interface.
a. Enter the VLAN interface.
interface VLAN2
b. 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
c. 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
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
Step 8 To configure which version of Internet Group Management Protocol (IGMP) the router uses, use the ip
igmp version command.
Router(config-if)# ip igmp version 3
