Implementing Cisco IP Routing (CCNP ROUTE, legacy) — Question 188

When configuring EIGRP to run across a 56 Kbps serial PPP link, what command do you need to put under the serial interface ensure proper convergence of
EIGRP routes?

Answer options

• A. bandwidth 56
• B. bandwidth 56000
• C. ip bandwidth-percent eigrp 1 56

Correct answer:

Explanation

The correct answer is C, as the 'ip bandwidth-percent eigrp 1 56' command allocates a percentage of the bandwidth for EIGRP, which is necessary for proper route convergence. Option A only sets the bandwidth to 56 Kbps but does not define a percentage for EIGRP. Option B incorrectly sets the bandwidth to 56000, which does not correspond to the actual link speed.
