Designing Cisco Enterprise Networks (ENSLD) — Question 133

An engineer is designing a BGP network for a large customer. To permit efficient scaling, the BGP domain is split into clusters. Which peering solution should be used between the route reflectors in different clusters for the BGP routes to be propagated appropriately?

Answer options

• A. The route reflectors should be made dents of each other.
• B. The route reflectors should be nonclients with regards to each other.
• C. The route reflectors should not have any kind of BGP peering.
• D. The route reflectors should have peering through another nonclient router.

Correct answer: B

Explanation

The correct answer is B because route reflectors in different clusters should be configured as nonclients to each other to maintain proper route propagation without creating a loop. The other options do not support the required BGP route propagation structure for effective scaling in the network.
