Display information about BGP routes whose AS-path matches the specified regular
expression. Accepts a single regular expression element. 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 quote-regexp and show bgp ipv6 quote-regexp commands display
similar information.
To display information about routes whose AS-path matches the specified regular
expression:
host1#show ip bgp quote-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)

Field Description
Name of route map that specifies routes to be advertised when
routes in conditional route maps are matched
Name of route map that specifies routes to be matched by routes
in the BGP routing table
Position of the specified advertise route map in a list of advertise
route maps configured for a particular peer within the same
address-family. A lower sequence number has a higher priority; that
route map is processed before one with a higher sequence number.
Status of the routes specified by the route map, advertise (route
map condition has been met) or withdraw (route map condition
has not been met; regardless of this status, the specified routes
might be governed by another route map with a lower sequence
number and actually advertised or not according to that map
