The following display examples are from Egress Router 5. Displays are shown for the show mpls rsvp session and show mpls rsvp session detail commands.
The display for Egress Router 5, shows an Egress Detour (DE) path and a path without a code that identifies a protected path. Both paths are shown from Ingress Router 4 at Loopback IP address 10.4.4.4 to Egress Router 5 at Loopback IP address 10.5.5.5. The primary path traverses Transit Routers 2 and 6. In the case of the DE path, a reroute sends traffic through Transit Routers 3 and 1.

The following example displays the output from Egress Router 5 using the show mpls rsvp session detail command. This command provides additional details about the paths described in the output from the show mpls rsvp session command.
For the DE path, two PLR and Avoid Node ID pairs are shown labeled [1] and [2]. In both the Point of Local Repair (PLR) is at IP Address 10.13.13.1 which is the interface to the primary path on Ingress Router 4. The Avoid Node for pair [1] is IP address 10.13.13.2 on Transit Router 2 and the Avoid Node for pair [2] is IP address 10.18.18.2 on Transit Router 6.
The "Fast Reroute" field indicates that the primary path has been configured for one-to-one backup.
There is no "Explicit path hop count" field for either route because Egress Router 5 is the destination of the path.
