Create the VLT domain
A VLT domain requires an ID number. Configure the same VLT domain ID on both peers. For more information, see the VLT domain
section. The no vlt-domain command disables VLT. Disabling VLT can cause loops in the network. Hence, use the no form of the
command cautiously.
1. Configure a VLT domain and enter VLT-DOMAIN mode. Configure the same VLT domain ID on each peer, from 1 to 255.
vlt-domain domain-id
2. Repeat the steps on the VLT peer to create the VLT domain.
Peer 1
OS10(config)# vlt-domain 1
OS10(conf-vlt-1)#
Peer 2
OS10(config)# vlt-domain 1
