Monitoring MPLS TE
show mpls traffic-eng autoroute
router#
• Shows tunnels that are announced to IGP, including interface, destination, and bandwidth
show ip cef network [mask]
router#
• Shows network entries in the Forwarding Information Base (FIB) to verify that IP traffic is forwarded through tunnel interface
show ip cef vrf vrf-name network [mask]
router#
• Shows VRF network entries in the FIB to verify that MPLS VPN traffic is forwarded through tunnel interface
