Managing the Routing Table

You can clear all routes from the IP routing table, and then enable the owning
protocols BGP, OSPF, RIP to reinstall the routes.
clear ip routes
ip refresh-route
Regular Matched AS-Path or Community
Expression Attribute
{41 19} (AS-path attribute only) Includes the
AS-set or AS-seq {41 19}
101 102 | 103 105 Includes either sequence 101 102 or
sequence 103 105
_200_ Includes the number 200 (as opposed
to the pattern consisting of numeral 2,
numeral 0, numeral 0)
Our implementation of regular
expressions is not literal. Substring
matching is enabled by default.
Specifying 200 (no underscores) results
in a match on 200 and on 2005. The
underscore metacharacter disables
substring matching.
Use to clear all routing entries or a specified entry from the IP routing table.
Example
host1#clear ip routes
There is no no version.
See clear ip routes.
Use to reinstall routes removed from the IP routing table by the clear ip route
command.
Example
host1#ip refresh-route
