300-440 Question 134
Select 3You are configuring a BGP session between two routers in an enterprise network. The routers are required to exchange both IPv4 and IPv6 routes. During the configuration of address families, which action must you take to ensure proper route exchange?
- A
Enable the IPv4 and IPv6 address families under the BGP routing process.
- B
Activate the neighbor under both IPv4 and IPv6 address families.
- C
Assign a route-map to the IPv4 address family only.
- D
Manually configure the next-hop address for IPv6 routes.
- E
Verify that the BGP neighbor is established with the correct Remote AS.
Show answer and explanation
Correct answers: A, B, E
Explanation
In BGP, each address family (IPv4 and IPv6) must be explicitly enabled within the BGP process for routes to be exchanged. Neighbors must also be activated under each address family to properly exchange routes. Additionally, the BGP session must be established with the correct Remote AS for successful communication. These steps ensure proper configuration for dual address family support in BGP.
- A. Correct.
Correct: To exchange IPv4 and IPv6 routes, you must explicitly enable both address families in the BGP process.
- B. Correct.
Correct: For BGP peer relationships, neighbors must be activated under each address family (IPv4 and IPv6) for route exchange.
- C. Incorrect.
Incorrect: Assigning a route-map is optional and not directly required for enabling address families.
- D. Incorrect.
Incorrect: While next-hop self may be a consideration in some scenarios, it is not a mandatory step for enabling IPv4 and IPv6 route exchange.
- E. Correct.
Correct: The BGP session must be established with the correct Remote AS for both IPv4 and IPv6 route exchange to occur.
