We have a few NPE-G1s out there as well with 1GB of memory and they are
more than capable of handling a full internet route table. Memory is
basically the same as what the others have posted. Feature wise we're
not really doing anything fancy so CPU utilization is fine.
One question I'd like to ask is whether anyone would ever consider using
one of these as a gateway towards your upstream transits pushing over
500Mbps of bandwidth?

Hi Mick,
FYI a 7206VXR-NPE-G1 loaded with 1Gig only consumes around 250Mb of
its memory for a full BGP table (around 271K routes without
filtering). See our router stat here

hope this gives you a clue if 512Mb will be able to handle full BGP table.

We need to shift some routers around in our network, and we have a couple of
7206-VXR routers with NPE-G1 which we'd like to redeploy into a situation
where they'll need to take the full public BGP table.
Currently they have 512MB of RAM, and the NPE-G1 appears to top-out at 1GigB
of RAM. Can anyone tell me if I can do the full table on 512 MB, or if I
need upgrade to !Gig, or is running the full table on a 7206-VXR a lost
cause anyway?
I'd run some tests, but it's going to be pain to get one of the 7206 to
where we can use it for testing without shuffling a bunch of stuff around.
I'd really like to know if it's going to function before going to all of
that work, so I'm hoping someone on this list can offer me a clue...
