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. > I would be interested in actual "it works/it doesn't" > commentary (and possible explanation of "it doesn't", if > that's the case) involving this particular router from > some sizeable ISP or other.

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.. <Whole bunch of Multicast USENET stuff cut> ----------------------------------------------------------- James 'J.D.'
