i wonder if any1 has a 7206VXR/NPE-G1 serving more than 10k sessions in
PRODUCTION (not the test- and/or lab-figures)
if yes, i'd be very intrested in what IOS you're using - and what

btw: we were using 7206VXR/NPE-400 - no special features enabled, just doing
plain "PPP-in-L2TP-termination" and did not manage terminating more than 4k
sessions (cisco claims 8k)...

that's the reason, why we're interested in "real-life-figures" of the NPE-1
(we've reached 6k - causing around 30% cpuload - no problems so far - but as
history shows, cpuload is not rising linear compared to the number of
sessions, we really doubt being able to do 16k sessions...)

tnx & greetz,

I'm a bit partial considering I work for Cisco but the 7206 with NPE-G1
should at the very minimum be at par with the capabilities of a SMS 1800 (is
that what you are looking at?) if not surpass it.  The 7206 can do the
following which the low-end Redbacks can't:

Per-user firewall
16k active sessions
Service Selection
ATM based Dynamic Bandwidth Selection

I'm sure I missed some more stuff.  You mentioned that the RB looks more
interesting, what specifically are you referring to?  I have to admit,
sometimes Cisco marketing/product capability definitions aren't as good as
they should be so I can easily see how one might miss a lot of the features
Cisco has.

Hope that helps a bit.
