Question 14

The configuration shown is performed on R2 to filter all incoming routes. Suppose there is a BGP route with the AS_Path attribute of [100200300400] on R1 that needs to be sent to R2. Please help the network administrator to adjust the AS order in the AS_Path attribute of the route on R1 to ensure that the route entry will not be filtered by the routing policy of R2____, ____, ____, ____.
