[nsp] ip cef

[James Galliford]

I believe that if the router does not have the route in its CEF table
that it process switches the first stream and therefore you'll see the
entry in the ip cache.  After the router knows the path and determines
the optimum switching method, it will then create an entry in the CEF
table for the path.  The path will then be invalidated from the route
cache.

This is to the best of my understanding of course.

Thanks.

Hi James!!!

          You are right. Now I see less entries in the table, but I
thought that all the packets would be cef switched. Why not? Thanks!!!

Hugo,

Whenever any packet is process switched you will see an addition to the
# of adds in the ip cache output.

You are probably seeing a much lower # of entries in the route cache
since turning on cef though correct?  If not, maybe CEF is not running
on all interfaces?

Thanks.

Hi!!!


             Just an easy question. I have just enabled Ip cef on my
router, but I still see new entries in the cache table when I execute
the "show ip cache" command. Could someone tell me if this is the right
way of cef working? Thanks!!!

Regards
