E.
Configure remove-private on advertisements from AS 64500 toward AS 64499
Answers
E.
Configure remove-private on advertisements from AS 64500 toward AS 64499
Suggested answer: B, D, E

Explanation:

The problem in this scenario is that R1 and R8 are not receiving each other's routes because of private AS numbers in the AS path. Private AS numbers are not globally unique and are not advertised to external BGP peers. To solve this problem, you need to do the following:

Configure loops on routers in AS 65412 and advertise-peer-as on routers in AS 64498. This allows R5 and R6 to advertise their own AS number (65412) instead of their peer's AS number (64498) when sending updates to R7 and R8.This prevents a loop detection issue that would cause R7 and R8 to reject the routes from R5 and R62.

Configure remove-private on advertisements from AS 64497 toward AS 64498 and from AS 64500 toward AS 64499. This removes any private AS numbers from the AS path before sending updates to external BGP peers.This allows R2 and R3 to receive the routes from R1 and R4, respectively3.
