Name
ip route-cache — interface
Synopsis
ip route-cache [cbus] [flow] [same-interface] [cef] [distributed] no ip route-cache
Configures
The route cache for an interface
Default
Enabled for most interfaces
Description
A route cache stores a route in a temporary table for the duration of a network session. When the session is completed or the session times out, the routing entry is removed from the route cache. The no form of this command disables the route cache, which causes the router to look up the route for each packet of the network session. In some applications, this can be the desired behavior; see Chapter 8.
