Case 12: Configure an AS_Path filter named s12 and allow Router B to accept only routes
carrying an AS_Confed_Set with 65101.
[RouterB] ip as-path-filter s12 permit \[.*65101.*\]
[RouterB] display bgp routing-table as-path-filter s12

The preceding command output shows that the BGP routing table contains only the route
carrying an AS_Confed_Set with 65101.
Case 13: Configure an AS_Path filter named s13 and allow Router B to accept only routes
carrying an AS_Confed_Set in which 65011 is the rightmost AS number.
[RouterB] ip as-path-filter s13 permit _65011\]
[RouterB] display bgp routing-table as-path-filter s13
Total Number of Routes: 0
The preceding command output shows that the BGP routing table contains no routes. Although
the route to 2.2.2.0/27 carries an AS_Confed_Set with 65011, 65011 is not the rightmost AS
number. As a result, this route is also discarded.

8.26 Maintaining BGP

Maintaining BGP involves resetting a BGP connection and clearing BGP statistics.
8.26.1 Configuring BGP to Record Peer Status Changes and Event
Information
After you configure the Border Gateway Protocol (BGP) to record peer status changes and event
information, BGP keeps logs when the peer status changes or an event occurs.
