[c-nsp] Does the entire BGP routing table for IPv6 fit on a Cisco 2600 with 64 MB of DRAM?

This is a bit tight.  On my good old 4700M, the "BGP router" process,
which is carrying all of IPv6, needs 6.5 Mbyte of RAM.  64 Mb total, 17 Mb
free.

*But*: "12.3 IP Plus" IOS for 2600 will likely eat much more RAM to start
with, so it might already be tight.

... and that will be a bigger problem.  The 2600 is *slow*, so chances
are you won't be able to tunnel enough IPv6 through it to even satisfy 
a single 16M ADSL link...  and you won't be happy with "proof-of-existance-
but quite slow" IPv6.
