JN0-281 · Question #18

Referring to the exhibit, which statement is correct?

The correct answer is B. The configuration will commit successfully and BGP group 1 will operate as EBGP. In the exhibit, BGP is configured with local AS 65101 and a neighbor at 172.16.1.1 in peer AS 65201. This setup involves two different Autonomous Systems (AS), indicating an External BGP (EBGP) configuration. EBGP is used between routers in different ASes. In this case, the…

Explanation

In the exhibit, BGP is configured with local AS 65101 and a neighbor at 172.16.1.1 in peer AS 65201. This setup involves two different Autonomous Systems (AS), indicating an External BGP (EBGP) configuration. EBGP is used between routers in different ASes. In this case, the local AS is 65101 and the peer AS is 65201, meaning the BGP session is EBGP. IBGP is used between routers within the same AS, which is not applicable here as the AS numbers are different. BGP Group Configuration: The configuration does not require a type external parameter because Junos OS automatically recognizes the session as EBGP when the local and peer AS numbers are different. The BGP session will operate as EBGP, and the configuration will commit successfully.
