7206 NPE-G2 with 4 full table feeds

Hi

I have an application where I have a 7206 with NPE-G2 (1G RAM) that
currently has a full table from an eBGP peer and a full table from a
co-located IBGP peer. I want to mesh this guy to two other IBGP peers
that will also send their full tables. There is roughly 400Mbps (adding
both direction) with an OSPF process (<30 routes) and an ISIS process
(<20 routes).

I haven't been very successful at finding real life BGP scaling for this
platform and was hoping that someone out there may be doing something
similar (4 x full table feeds with ~400Mbps) and can provide feedback on
performance and/or stability. I have soft reconfig inbound enabled on
the current two feeds, I assume that this will make a difference in this
application with regards to available memory for all 4 feeds?

Thanks in advance

Eric

First of all - cisco-nsp@ is a better place to ask such question
and if you search archives of it, you'll find a lot of comments
for such config.

With 1GB of RAM you may run short (check current actual usage), but
I'd recommend in such situation to rely rather on the route refresh
standard capability, than the soft reconfig - it eats memory per-peer,
and with route refresh you can get almost the same, trading bandwidth
on the link for RAM in the RP. NPE-G2 can take 2GB of RAM, so if
that's going to stay I'd also recommend upgrading if you're running
short of memory either way. Or upgrade to ASR 1k and move into the
world of hardware-forwarding platforms.
