Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) — Question 48

Which statement about the Cisco MPLS TE forwarding adjacency feature is true?

Answer options

• A. It enables the MPLS core to use EIGRP as the routing protocol.
• B. It enables the Cisco MPLS TE tunnel to be advertised into the running IGP.
• C. It enables the tailend router to advertise routes to the headend router over the tunnel.
• D. It enables the headend and tailend routers to establish a bidirectional tunnel.

Correct answer: B

Explanation

The correct answer, B, is accurate because the Cisco MPLS TE tunnel can be advertised into the running IGP, enabling better integration with the network. Option A is incorrect as EIGRP is not specifically tied to MPLS TE forwarding adjacency. Option C misrepresents the functionality since route advertisements occur in the opposite direction. Option D is also misleading because it doesn't accurately describe the nature of the tunnel establishment in this context.
