I see, this is for a production network.
I am not sure how much of 100mb line you are looking to use, but if you don't
want to multihome, etc in the future, 3550 EMI should definately give you the
performance, as its hardware based, just watch out the system resources.
7200 Series VXR with NPE-300 or higher should be able to serve you quite well
for most applications. But if you are looking to push linerate of >= ~200Mbps
traffic to about gig worth of traffic, then NPE-G1 finally makes 7200 Series
useful again :)
Exactly how much traffic are you looking to push, not just in bits, but also in
packets is what you will need to determine. Are you looking to get multihomed
later and run BGP, etc, etc is another set of questiosn to keep in mind. I'd
personally prefer starting out with 7200 VXR in place as router, IMHO. Depends
on the NPE you have, 3550 will most likely give you more performance but at a
tough cost of smaller available resources/breathing room to work with (in terms
of feature set of the box) than with a 7200 router.
