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
Valid interfaces include: Ethernet (eth 0/1), PPP virtual interfaces (ppp 1), HDLC
virtual interfaces (hdlc 1), Frame Relay virtual sub-interfaces (fr 1.20), tunnel
interfaces (tunnel 1), and VLAN interface (vlan 1).
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 tunnel interface:
(config)#interface tunnel 1
(config-tunnel 1)#ip route-cache
Note
Using Network Address Translation (NAT) or the SROS firewall capabilities on an
interface requires process switching mode (using the no ip route-cache command).
