Setup Guide

Domain_1_Peer2(conf-if-po-100)# vlt-peer-lag port-channel 100
Domain_1_Peer2(conf-if-po-100)# no shutdown
Add links to the eVLT port-channel on Peer 2.
In Domain 2, congure the VLT domain and VLTi on Peer 3.
Congure eVLT on Peer 3.
Domain_2_Peer3(conf)#interface port-channel 100
Domain_2_Peer3(conf-if-po-100)# switchport
Domain_2_Peer3(conf-if-po-100)# vlt-peer-lag port-channel 100
Domain_2_Peer3(conf-if-po-100)# no shutdown
Add links to the eVLT port-channel on Peer 3.
Next, congure the VLT domain and VLTi on Peer 4.
Congure eVLT on Peer 4.
Domain_2_Peer4(conf)#interface port-channel 100
Domain_2_Peer4(conf-if-po-100)# switchport
Domain_2_Peer4(conf-if-po-100)# vlt-peer-lag port-channel 100
Domain_2_Peer4(conf-if-po-100)# no shutdown
Add links to the eVLT port-channel on Peer 4.
PIM-Sparse Mode Conguration Example
The following sample conguration shows how to congure 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, refer to PIM-Sparse Mode Support on VLT.
Examples of Conguring PIM-Sparse Mode
The following example shows how to enable PIM multicast routing on the VLT node globally.
VLT_Peer1(conf)#ip multicast-routing
The following example shows how to 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
The following example shows how to congure 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
The following example shows how to 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
