ip route-cache
Use the ip route-cache command to enable fast-cache switching on the interface. Use the no form of this
command to disable fast-cache switching and return to process switching mode.
Syntax Description
No subcommands.
Default Values
By default, fast-cache switching is enabled on all Ethernet and virtual Frame Relay sub-interfaces. IP
route-cache is enabled for all virtual PPP interfaces.
Command Modes
(config-interface)# Interface Configuration Mode required
Valid interfaces include: Ethernet (eth 0/1), virtual Frame Relay sub-interfaces
(fr 1.16), virtual PPP interfaces (ppp 1), and loopback interfaces.
Functional Notes
Fast switching allows an IP interface to provide optimum performance when processing IP traffic.
Usage Examples
The following example enables fast switching on the loopback interface:
(config)#interface loopback 1
(config-loop 1)#ip route-cache
Note
Using Network Address Translation (NAT) or the Secure Router OS firewall capabilities on
an interface requires process switching mode (using the no ip route-cache command).
