JN0-649 Exam - Question 51


There are two BGP routes to 10.200.200.0/24 received from two external peers. Route 1 comes from a neighbor with a router ID of 10.10.100.1 and a peer IP address of 10.10.30.1, and route 2 comes from a neighbor with a router ID of 10.10.200.1 and a peer IP address of 10.10.50.1. Both routes have the same MED value, origin value, AS path length, and local preference number.

In this scenario, which statement is correct about the active route?

Show Answer
Correct Answer: C

When BGP routes have identical attributes such as MED value, origin value, AS path length, and local preference number, the decision for the active route moves to the next criteria: the router ID. The route with the lowest router ID is preferred. In this case, Route 1 has a router ID of 10.10.100.1, which is lower than Route 2's router ID of 10.10.200.1. Therefore, Route 1 will be the active route based on the router ID.
