Chapter 4 Configuring the Cisco MWR 2941 Router Using the CLI
Configuration Sequence
Step 2 Enter configuration mode.
Router# configure terminal
Step 3 Complete the following steps to create an access list to permit specific Multicast Groups for use with the
static RP 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 command to allow traffic from multicast groups. Repeat this step for each each
network from which you want to allow traffic.
Router(config)# access-list 2 permit 239.193.0.0 0.0.255.255
Router(config)# access-list 2 permit 239.194.0.0 0.0.255.255
Note Access lists are required for sparse mode with a single static RP; ensure that you configure ACLs
before completing the Multicast configuration. 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 By default, the IP address of the outgoing interface of the designated router (DR) leading toward the RP
is used as the IP source address of a register message. If you want to configure another IP source address,
use the ip pim register-source command to specify another interface.
Router(config)# ip pim register-source Loopback0
Step 6 Use the ip pim rp-address command to statically configure a PIM rendezvous point (RP) for a multicast
group.
Router(config)# ip pim rp-address 10.2.1.1 5 override
Step 7 Follow these steps to configure the Ethernet backhaul interface.
a. interface type number
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. If you want to enable only the Protocol Independent Multicast (PIM) version 2 on the interface, use
the no ip pim version 1 command to disable PIM version 1.
Router(config-if)# no ip pim version 1
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
