You are designing a WAN network solution with EIGRP based on VPLS. The interface speed is 10 Mb/s, but the access rate of the WAN connection is 256 Kb/s. What should you include in the network design, in order to avoid potential issues with EIGRP?

Question

Accepted Answer

B. Set the interface bandwidth to match the access rate. EIGRP's composite metric formula uses the minimum bandwidth along a path, so leaving the interface bandwidth at 10 Mb/s causes EIGRP to compute artificially favorable metrics and potentially flood the 256 Kb/s link with more traffic than it can carry. Setting the interface bandwidth to 256 Kb/s aligns EIGRP's metric calculations with the real access rate and prevents the routing process from oversubscribing the WAN link.

Answer

A. Tag outbound EIGRP traffic and have the WAN provider add it to the priority queue. Tagging and prioritizing EIGRP traffic with the WAN provider does not correct the underlying bandwidth mismatch that causes incorrect metric calculations.

Answer

C. Limit traffic to the access rate with interface traffic shaping. Traffic shaping limits the aggregate rate but does not fix EIGRP's metric calculation, which remains based on the incorrect 10 Mb/s interface bandwidth value.

Answer

D. Limit EIGRP traffic to the access rate with a policer. Policing EIGRP traffic drops routing packets when the rate is exceeded, which would destabilize neighbor adjacencies rather than resolving the root cause of the bandwidth mismatch.
