MPLS and Segment Routing

Question Image

Refer to the exhibit. Router 1 has tried to establish a Cisco MPLS TE tunnel to router 2, but the tunnel has failed. Which statement regarding this configuration is true?

  • A Router 1 must define an explicit path to router 2
  • B Router 1 and router 2 must define the RSVP bandwidth reserved on the physical interfaces
  • C Router 2 must have a tunnel interface created with router 1 as the destination
  • D Router 1 must have Cisco MPLS TE enabled on interface gigabitethernet0/1
Explanation

MPLS TE tunnel signaling must be enabled on each physical interface that carries the TE tunnel. Router 1 has RSVP bandwidth configured on GigabitEthernet0/1 but lacks mpls traffic-eng tunnels on that interface, preventing the tunnel from being established. An explicit path is optional because MPLS TE can use a dynamically calculated path, and the tunnel headend—not the tailend—creates the tunnel interface.
