[c-nsp] BGP hardware requirements

[Roman Bestuzhev]

It seems that 2851 is more than enough to route two links at 1 or 2 Mb/s. As
Cisco says, 2851 is capable to route at speed of 112 Mb/s, but in real world
you should devide this value by 2 at least.

As I see this devise has 256 Mb of memory. It is enaugh for default and
several specific routes but not enaugh for full view. For full view you may
want to consider to add 1Gb of memory, or 512 Gb at least for single full
table.

And finally, to support BGP you need another IOS, not IP BASE which can
support only static routes and RIP, if I remember correctly. Look at
adventerprise version of IOS.
