CEF and ip route-cache same-interface

[gcyeaw]

We have a point-to-multipoint frame relay configuration with CEF enabled. Should we still use the 'ip route-cache same-interface' command to reduce the process switching of site to site traffic?

All configured on a single multipoint interface, or configured as subinterfaces? If they are on subinterfaces, you shouldn't need this. If they are on one interface, then I would turn it on.

It is a single interface (ospf point-to-multipoint).

Then you'll need to turn on route cache same interface.
