Question Image

You receive the 203.0.113.0/24 route from both upstream ISPs. You are asked to ensure that ISP A is the preferred ISP for traffic sent to the 203.0.113.0/24 network from devices in AS 65512.

Referring to the exhibit, which two statements accomplish this behavior?

Choose two
Explanation

BGP uses LOCAL_PREF within an autonomous system to select an outbound path, and the route with the higher preference is selected. Setting ISP A’s learned route above the default value of 100, or setting ISP B’s learned route below 100 while ISP A remains at 100, makes the ISP A path preferred throughout AS 65512.
