Create the VLT domain
A VLT domain requires an ID number. Congure 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 Congure a VLT domain and enter VLT-DOMAIN mode. Congure 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.
