Implementing Cisco Enterprise Advanced Routing and Services (ENARSI) — Question 273

In order to connect between disparate OSPF and EIGRP portions of a network, mutual route redistribution has been configured. What are two disadvantages of doing this? (Choose two.)

Answer options

• A. Prone to routing loops if not done correctly
• B. Differing metrics between the routing protocols could result in sub-optimal routing.
• C. Route redistribution is not supported on most Cisco router platforms.
• D. Increased convergence times.

Correct answer: A, B

Explanation

The correct answers A and B highlight significant risks of route redistribution, where incorrect configurations can lead to routing loops and differing metrics can cause inefficient paths. Option C is incorrect because route redistribution is generally supported on Cisco routers. Option D, while true, is less directly related to the inherent disadvantages of route redistribution compared to the potential for loops and metric issues.
