[c-nsp] Adequate RAM in 7206VXR/NPE-G1?

[Rick Kunkel]

Hello all,

We've got a 7206VXR/NPE-G1.  In it, we have the following modules:

PA-T3
PA-A3-T3

The PA-T3 is totally unused.  Nothing plugged in.

The PA-A3-T3 has an ATM DS-3 from Verizon to aggregate our DSL customers.

On the NPE-G1, one GigE port is taken by an 802.1q trunk to a bunch of
colo customers.

Another GigE port is taken by a 100 Mbps Ethernet connection ot the
Internet.

We get full routes from the upstream connected to the above port.

My question is about RAM.  If I'm reading the show ver correctly, we've 
got 256M of RAM.  I was recently told that this is like the BARE minimum 
for a full routing table.  And considering other factors of its use, 
probably rather lacking.

Can anyone verify or refute this?

Here's a show ver:

The 3MB free looks a little suspicious, but on the other hand, it hasn't 
hit zero before.

Any input is appreaciated....

Thanks,
