Monitoring BGP Routes with Matching AS-Paths and Regular Expressions for Multiple
Regular Expressions
Purpose Display information about BGP routes whose AS-path matches the specified regular
expression elements. Accepts one or more regular expression elements. Report whether
the indirect next hop of a route is unreachable; if not, display the IGP cost to the indirect
next hop.
Regular expressions match numbers for which the specified path is a substring—for
example, if you specify 20, 200 matches because 20 is a substring of 200. You can
disallow substring matching by using the underscore (_) metacharacter to constrain
matching to the specified pattern, for example, _20_.
The show ip bgp regexp and show bgp ipv6 regexp commands display similar
information.
Action To display information about routes whose AS-path matches the specified regular
expression element:
host1#show ip bgp regexp ^200
Local router ID 192.168.1.232, local AS 100
6 paths, 3 distinct prefixes (324 bytes used)
3 paths selected for route table installation
7 path attribute entries (872 bytes used)
