show mpls traffic-eng tunnels
MP-743
Cisco IOS Multiprotocol Label Switching Command Reference
January 2010
In Cisco IOS Release 12.2(33)SRE and later releases, P2P and P2MP MPLS TE tunnels display “reroute
pending” during reoptimization until the new path is used for forwarding. The “reroute pending” status
is not displayed during the delayed clean operation. There is no change to data forwarding or tunnel
creation. You might see the “reroute pending” status for a shorter time. In the following example, the
“reroute pending” message appears, but the “delayed clean” message does not.
Router# show mpls traffic-eng tunnels tunnel 534
Name: Router_t534 (Tunnel534) Destination: 10.30.30.8
Status:
Admin: up Oper: up Path: valid Signalling: connected
path option 10, type explicit PRIMARY_TO_8 (Basis for Setup, path weight 30)
Change in required resources detected: reroute pending

Examples The following is sample output from the show mpls traffic-eng tunnels brief command. It displays
brief information about every MPLS TE tunnel known to the router.
