Being able to take a full BGP table in a Cisco is simply a matter of

I just accidentally ran into an ugly surprise turning up some 4006/SupIV’s with full tables. There’s a 128K hardware fib table limit. Crack it, and CEF shuts down. There’s an unallocated 350M block lying around. Took the TAC a while to point out the fine print, and now I face the pleasure of a forklift upgrade.
