I've got a Cisco 2620 with 2 T1 Wic's. Each WIC has a connection to a different ISP that I plan to run BGP on. I'm also use the Firewall Feature set to do NAT and protocol inspection for my network.
The box currently has 64mb of ram and appears to have plenty of memory available when I do a 'show memory'
Router#sh mem
Head Total(b) Used(b) Free(b) Lowest(b) Largest(b)

I/O 3400000 12582912 1715448 10867464 10812876 10867420
If I just get summary routes from each ISP (that is just their network) they say the box should have at least 64mb of ram. I want to take into account the Firewall Featureset plus the BGP requirement in my memory calculations.
Is 64mb of ram enough?
Does a 2620 have enough horse power to handle all this? (If not, what should I be looking at to do this?)
