I'm using a 7606 with sup 720 and policy feature card 3B.
This PFC supports a maximum number of 239k CEF table entries. I know that a PFC card upgrade will take me to 1M CEF entries but this may not be an option in the near future and I could be running out of space in a couple of months.
This is an Internet facing edge router, so the vast majority of this is taken up by BGP routes.

Is there a CEF table aging time?
How do other people manage their CEF table size when PFC upgrade is not an option?
