Note: The command show ip route <cr> can also be used to verify the information above as well as
static routes and direct connections.
6.3.3 show vlt
This command is used to validate VLT configuration status on leaf switches in this topology. The Inter-chassis
link (ICL) Link Status, Heart Beat Status and VLT Peer Status must all be up. The role for one switch in the
VLT pair is primary and its peer switch (shown here) is assigned the secondary role. Ensure Peer-Routing is
shown as enabled.
