Cisco IOS: BGP AS-Path Access List
Let me show you an example why we need AS-Path Access-List, in addition to Regular Expressions, in BGP.
1:16 Example Condition 1: show ip bgp regexp ^3$
1:27 Example Condition 2: show ip bgp regexp ^3 2$
2:03 Example Condition 3: show ip bgp regexp _202_
2:40 Combine them all together: show ip bgp regexp ^3$|^3 2$|_202_
4:29 List defined AS-Path Access Lists: show ip as-path-access-list
4:37 Creating AS-Path Access List 500.
6:11 To apply AS-Path Access List in BGP, command is: show ip bgp filter-list 500
6:21 AS-Path Access List 500 produces exactly the same results.
7:45 The only caveat for AS-Path Access Lists is we must have configuration privilege.
