[c-nsp] 7609_uRFP Performance Impact

[Victor Lyapunov]

Hello all

I am examining the prospect of enabling urfp in a cisco 7609 / RSP 720
platform, for subscriber facing
interfaces.

My needs are covered by plain strict urpf (no acls, or multipath
support is needed). According to documentation traffic failing urpf is
supposed to be handled in hardware.

In my setup the mls rate-limiter for unicast ip rpf-failure is
disabled (needed the rate limiter resources for other
traffic types)

Is the "mls unicast ip rpf-failure" rate limiter needed in the case of
strict urfp? or its usage is limited to
packets failing uRFP check when ACL / multipath is needed?

Thnx
