In order to hit performance marks that are excellent with IPSec you will
need not only a spiffy NPE but the PA-VAM or PA-ISA.  Be aware that the
PA-VAM may not work with the latest and greatest IPSec image.  I picked
up a 7206VXR VPN bundle from Cisco last month and the only IOS supported
was 12.1(9)E.  This may have changed with 12.2(13)T - do your homework
and test it.
With the VAM and the NPE-400 Cisco claims ~150Mbps throughput.  Be sure
to top it off with memory - if you are running lots of tunnels you will
need the space.  I haven't tested the performance myself and do not know
how the split bus of the 7200's will affect performance of one PA or
another depending on where it's plugged in.  Not all my questions have
been answered...
The VPN bundle lists for $23,500 - apply your discount.  That gives you
fastethernet interfaces(2), the PA-VAM, and the NPE-400.  You'll have to
pay for more....  If you can use a newer IOS version (come ON Cisco...)
you can run the easy VPN server on the box and make life so much easier.
The 12.1 code does a good job of working with x.509 certs, but there is
a lot of command change between 12.1(9) and 12.2(13)T, so watch your
configurations carefully and be prepared to rewrite things between
versions.
The PA-ISA does run with a piece of 12.2 code (I have a client using it)
and does just fine.  In the case of both accellerators there is no AES
support that I am aware of.  If you are looking for AES, the software
crypto engine is supposed to support it in 12.2(13)T on some(all?)
platforms and I've heard that there's a new crypto hardware piece in the
works to support it also.

Just a thought:  Depending on your application, you may consider buying
two smaller VPN enabled routers (3600 or 2600) and using multiple
tunnels frome each site to the hub for layer 3 based load balancing and
fault tolerance.  They are routers, make 'em route!  (Or heck, just buy
2 7206 bundles... :)  You may get performance every bit as good, with
availability numbers that make you look like an uber-star to the boss.

thanks for the info.

have you or anyone else any idea what configuration it takes for a 7200
router to be comparable in performance to a PIX 515 when it comes to a
site-to-site VPN?  for example, would a 7204VXR by itself be enough
(over more than enough, for that matter) to meet the packet throughput
performance of a PIX 515 on a 3DES ipsec tunnel set up site-to-site?  i
can't seem to find pps performance specs for the 7200 series...

thanks,

ed

     The primary differance is the NSE is it is only supported in the 
7200VXR and incorporates the PXF processor for accelerated packet
switching.

   To get VXR performance you must use at least a NPE300 and you get a 
MIX backplane, good for voice stuff.  Also the VXR gives you increased 
backplane bandwidth capabilities.

   With the new NPE-1G you no longer have any bandwidth point
limitations!
