Group,
One of task say configure AS200 so that it will only send out traffic from
this link to AS100 and it's directly connected customer.
I configured as-path access list as below but still R2 is receiving routes
from other than 100 and 54. what could be the problem ?
*R2#show ip as-path-access-list
AS path access list 58
permit ^100(_[0-9]+)?$
*
R2#show running-config | section bgp
