Question

On Cisco routers, is it possible to have equal cost multipath static routes ?

If so, how ?

Thanks.

Answer 1

Yes. IOS router with will load share between static/default routes. Just enter two static routes to the same destination, pointing to different next-hops:

ip route 10.3.1.1 255.255.255.255 10.0.0.2
ip route 10.3.1.1 255.255.255.255 10.0.0.6

(these nex-hops of course should know a way to the destination address/net)
Load sharing behavior is dependent on packet switching method used for some particular flow.

With IOS fast switching – you can load-share only per-destination (ip-src – ip-dst pair).
With CEF you can use two load sharing algorythms – per-packet and per-destination.

Use this global config command to turn CEF on:

ip cef

Use these commands on the incomming interface to change CEF load sharing algorythm:

ip load-sharing per-packet
ip load-sharing per-destination

Use this command to check load sharing status for some particular prefix:

sho ip cef <prefix> detail
