The following example verifies that RSVP and MPLS TE are enabled and coexist on the headend device (10.0.0.2 in the figure above):
Device# show ip rsvp
RSVP: enabled (on 3 interface(s))
RSVP QoS enabled <-------
MPLS/TE signalling enabled <------
Signalling:
Refresh interval (msec): 30000
Refresh misses: 4
...
The following example verifies that RSVP and MPLS TE are enabled and coexist on the tailend device (10.0.0.3 in the figure above):
Device# show ip rsvp
