Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) — Question 162

A network engineer has configured TE tunnels in the MPLS provider core. Which two steps ensure traffic traverse? (Choose two.)

Answer options

• A. ECMP between tunnels allows RSVP to function correctly.
• B. The IGP metric of a tunnel is configured to prefer a certain path.
• C. A tunnel weight is configured in SPF database the same way as a native link.
• D. Static route is the only option for directing traffic into a tunnel.
• E. Forwarding adjacency feature allows a tunnel to be installed in the IGP table as a link.

Correct answer: B, E

Explanation

Option B is correct because configuring the IGP metric of a tunnel to prefer a certain path helps in effective traffic routing. Option E is also correct since the forwarding adjacency feature allows the tunnel to be treated like a link in the IGP table. Options A, C, and D are incorrect as they do not correctly describe necessary steps for traffic traversal through TE tunnels.
