I'm running into a problem with a 7507 router running 12.4 where any vlan subinterfaces inside a VRF is being process switched instead of CEF or fast switched. I've verified that the source and destination addresses are valid in the cef FIB but for some reason it's falling back to process switching. Any ideas?
I've attached the config and the output of all the show commands I can think would be related.
For a test instance, packets from source 10.1.25.5 traveling to 126.96.36.199 are process switched, as are packets from 192.168.0.35 to 10.1.27.42.
