Route Summarization Scenario
In Figure
Router B and Router C, the BGP routing table on Router A is as follows:
[RouterA] display bgp routing-table
BGP Local router ID is 189.6.2.2
Status codes: * - valid, > - best, d - damped,
Total Number of Routes: 5
*>

Case 7: Configure an AS_Path filter named s7 and allow Router A to discard routes that pass
through AS 65011.
[RouterA] ip as-path-filter s7 deny 65011
[RouterA] ip as-path-filter s7 permit .*
[RouterA] display bgp routing-table as-path-filter s7
BGP Local router ID is 189.6.2.2
Status codes: * - valid, > - best, d - damped,
Total Number of Routes: 3

300i
The preceding command output shows that the BGP routing table contains all routes except
those that pass through AS 65011.
Case 8: Configure an AS_Path filter named s8 and allow Router A to accept only the routes
carrying an AS_Sequence with 65011 and an AS_Set with 65101.
[RouterA] ip as-path-filter s8 permit .*65011.*\{.*65101.*\}
[RouterA] display bgp routing-table as-path-filter s8
BGP Local router ID is 189.6.2.2
Status codes: * - valid, > - best, d - damped,
Total Number of Routes: 1
