PIM-Sparse Mode Configuration Example
The following sample configuration shows how to configure the PIM Sparse mode designated router functionality on the VLT
domain with two VLT port-channels that are members of VLAN 4001.
For more information, see PIM-Sparse Mode Support on VLT.
Enable PIM Multicast Routing on the VLT node globally.
VLT_Peer1(conf)#ip multicast-routing
Enable PIM on the VLT port VLANs.
VLT_Peer1(conf)#interface vlan 4001
VLT_Peer1(conf-if-vl-4001)#ip address 140.0.0.1/24
VLT_Peer1(conf-if-vl-4001)#ip pim sparse-mode
VLT_Peer1(conf-if-vl-4001)#tagged port-channel 101
VLT_Peer1(conf-if-vl-4001)#tagged port-channel 102
VLT_Peer1(conf-if-vl-4001)#no shutdown
VLT_Peer1(conf-if-vl-4001)#exit
Configure the VLTi port as a static multicast router port for the VLAN.
VLT_Peer1(conf)#interface vlan 4001
VLT_Peer1(conf-if-vl-4001)#ip igmp snooping mrouter interface port-channel 128
VLT_Peer1(conf-if-vl-4001)#exit
VLT_Peer1(conf)#end
Repeat these steps on VLT Peer Node 2.
VLT_Peer2(conf)#ip multicast-routing
VLT_Peer2(conf)#interface vlan 4001
VLT_Peer2(conf-if-vl-4001)#ip address 140.0.0.2/24
VLT_Peer2(conf-if-vl-4001)#ip pim sparse-mode
VLT_Peer2(conf-if-vl-4001)#tagged port-channel 101
VLT_Peer2(conf-if-vl-4001)#tagged port-channel 102
VLT_Peer2(conf-if-vl-4001)#no shutdown
VLT_Peer2(conf-if-vl-4001)#ip igmp snooping mrouter interface port-channel 128
VLT_Peer2(conf-if-vl-4001)#exit
VLT_Peer2(conf)#end
