I hope in & 10.8 some Common Service will be Running (like http, ftp, etc.,)

You can write ACL based on Port based.

Hi ,

create extended access-list on B ..

access-list 101 permit ip host

access-list 101 permit ip host


create extended access-list on A.

access-list 101 permit ip

apply these on serial interfaces of the routers....
