Configuring IP Multicast Routing
Configuration Example
Switch(config)# interface vlan100
Switch(config-if)# ip pim passive
Switch(config-if)# exit
Switch(config)# interface GigabitEthernet0/20
Switch(config-if)# ip pim passive
Switch(config-if)# exit
Switch(config)# interface vlan100
Switch(config-if)# ip address 100.1.1.1 255.255.255.0
Switch(config-if)# ip pim passive
Switch(config-if)# exit
Switch(config)# interface GigabitEthernet0/20
Switch(config-if)# no switchport
Switch(config-if)# ip address 10.1.1.1 255.255.255.0
Switch(config-if)# ip pim passive
Switch(config-if)# end
To verify that PIM stub is enabled for each interface, use the show ip pim interface privileged EXEC command:
Switch# show ip pim interface
Address Interface Ver/ Nbr Query DR DR
Mode Count Intvl Prior
3.1.1.2 GigabitEthernet0/25 v2/SD 1 30 1 3.1.1.2
100.1.1.1 Vlan100 v2/P 0 30 1 100.1.1.1
10.1.1.1 GigabitEthernet0/20 v2/P 0 30 1 10.1.1.1
The following example shows how to configure a device (running IGMPv3) for SSM:
ip multicast-routing
ip pim ssm default
!
interface GigabitEthernet3/1/0
ip address 172.21.200.203 255.255.255.0
description backbone interface
ip pim sparse-mode
!
interface GigabitEthernet3/2/0
ip address 131.108.1.2 255.255.255.0
ip pim sparse-mode
description ethernet connected to hosts
ip igmp version 3
!
The following example shows how to enable static SSM mapping. In this example, the router is configured to statically
map groups that match ACL 11 to source address 172.16.8.11 and to statically map groups that match ACL 10 to source
address 172.16.8.10.
Switch(config)# ip igmp ssm-map enable
Switch(config)# ip igmp ssm-map static 11 172.16.8.11
Switch(config)# ip igmp ssm-map static 10 172.16.8.10
Switch(config)# end
The following example shows how to configure DNS-based SSM mapping:
Switch(config)# ip igmp ssm-map enable
Switch(config)# ip name-server 10.0.0.0
Switch(config)# end
The following example shows how to configure group address 239.1.2.1 to use SSM mapping for statically forwarded
groups on Ethernet interface 0:
interface ethernet 0
ip igmp static-group 239.1.2.1 source ssm-map
This example shows how to configure the address of the RP to 147.106.6.22 for multicast group 225.2.2.2 only:
