You will find that such a formula will require the
specific IOS, feature set available, feature set used,
routing protocol(s), interfaces, sub-interfaces, the
phase of the moon at installation... (Actually you
might not need sub-interfaces! ;)
Every formula I have ever seen fails miserably - the
one for EIGRP from Cisco reported that 1.5 MB would be
enough - we died with almost 40 free before the
installation.
Basically, if you are going to do BGP, EIGRP or OSPF
I'd max the memory - its cheap. Also, NAT, PAT,
access-lists and other features would tend to
influence my desire to load things up. Just as with
PCs, you're best bet is to have enough. Otherwise,
make a best guess, load it up and take a look - baring
in mind that new features may put you over the top.
