The entire BGP table is not copied into CEF. The entire routing table is.
Depending on your policy, your routing table should have fewer entries then
your routing table.
CEF is a all or nothing proposition since when you enable it, it is how the
router routes all unicast IP packets. You can't selectively pick a
switching path based on the prefix you are looking up.
128MB should be enough for two BGP peers and CEF. What problems are you
running into when you enable CEF?

Hi,
128 MB RAM on my 7206 NPE-200 isn't enough to run CEF it seems, with two
full BGP views. I don't think I need CEF for performance, but I do want
CEF for uRPF.
When you turn on "ip cef", I believe that copies the entire BGP table to
CEF?
I only need the customer static routes to copied to CEF, is that possible
on 12.0.14(S) ?
