5. Verify the configuration:
# Execute the display mpls te tunnel command on Switch A.
[SwitchA] display mpls te tunnel
LSP-Id Destination In/Out-If Name
1.1.1.9:6 3.3.3.9 -/Vlan1 Tunnel1
1.1.1.9:2054 3.3.3.9 -/Vlan4 Tunnel1
The output shows that two tunnels are present with the outgoing interface being VLAN-interface 1
and VLAN-interface 4. This indicates that a backup CR-LSP was created upon creation of the
primary CR-LSP.
# Execute the display mpls te tunnel path command on Switch A to identify the paths that the two
tunnels traverse:
[SwitchA] display mpls te tunnel path
