Virtual Link Trunking (VLT) | 975
Domain_2_Peer3(conf-if-range-te-0/16-17)# no shutdown
Next, configure the VLT domain and VLTi on Peer 4:
Domain_2_Peer4#configure
Domain_2_Peer4(conf)#interface port-channel 1
Domain_2_Peer4(conf-if-po-1)# channel-member TenGigabitEthernet 0/8-9
Domain_2_Peer4(conf)#vlt domain 1000
Domain_2_Peer4(conf-vlt-domain)# peer-link port-channel 1
Domain_2_Peer4(conf-vlt-domain)# back-up destination 10.18.130.12
Domain_2_Peer4(conf-vlt-domain)# system-mac mac-address 00:0b:00:0b:00:0b
Domain_2_Peer4(conf-vlt-domain)# unit-id 1
Configure mVLT 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 mVLT port-channel on Peer 4:
Domain_2_Peer4(conf)#interface range tengigabitethernet 0/31 - 32
Domain_2_Peer4(conf-if-range-te-0/16-17)# port-channel-protocol LACP
Domain_2_Peer4(conf-if-range-te-0/16-17)# port-channel 100 mode active
Domain_2_Peer4(conf-if-range-te-0/16-17)# no shutdown
PIM-Sparse Mode Configuration Example
The sample configuration below 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. Refer to
the figure in 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
