Well I know that on the IRX platform the router is not fast enough to
deal with light ammounts of updates with 5 or 6 sessions and still
forward packets.. I am told the on the PM3's that is handles it just
fine..
The IRX is old 3 years or so 386DX-40 based where the PM3 is 486/66
For instance when we reset a IBGP session when the session
establishes when loading the routes (15-20k) it will stop forwarding
for 5-10 sec.

It works.. I am very happy with it.. On the IRX platform it is not
ment as a backbone router but for customer connections it works
great. We have a few of them that are not accepting BGP routes but
are anouncing customer routes.. It seems to work real well. I hope to
get a PM3 in here to find out how well it works.. If the performance
is as good as I have heard and the fact that I can fit 6-8 full views
in 16 MB of ram... we might have a winner for some of our smaller
POP's..
Plus where space is not a big problem the IRX is a great price for a
2 T1 2 56k port router for customer connects..
