Your BGP router receives routes from two upstream ISPs: ISP A and ISP B.
In this scenario, which change would you make to prefer routes from ISP A?
Your BGP router receives routes from two upstream ISPs: ISP A and ISP B.
In this scenario, which change would you make to prefer routes from ISP A?
The local-preference attribute in BGP is used to prioritize routes within an autonomous system. A higher local-preference value indicates a more preferred route. By setting the local-preference attribute for routes received from ISP A to 200, which is higher than the default value of 100 used by routes received from ISP B, the BGP router will prefer routes from ISP A over those from ISP B.
The correct answer is: A. Set the local-preference attribute for all routes received from ISP A to 200 while all routes received from ISP B use the default local-preference value of 100. Explanation: The local-preference attribute is used to influence the BGP route selection process within an autonomous system. A higher local-preference value is preferred, so by setting a higher value for routes received from ISP A, the BGP router will prefer those routes over the ones received from ISP B.
A is correct
Can you explain why you think the A is incorrect?
