Hi Phil, To clarify. The sites that I'm considering using an HP 2610-48 as a router have <100 devices (6 remote sites resemeble this). The 3 remaining remote sites have 300-600 devices, but the routing switch at those sites is a 5300 (in one case) and 5400 (in the other two cases).
I defeinitely plan to set up ALL remote sites with a different subnet (as I already have in place). My bigger question was, would you still put the WAN link on a seperate network from EITHER the local or remote site. Make sense what I'm asking (I'm not sure I'm explaining it well)? Right now, I'm leaning towards keeping the fiber WAN links on a seperate network from the main site and remote sites (just like my T1s are on a seperate network) -- this way NO broadcast traffic at all crosses the WAN links ever. Thanks for the info on the "light" layer 3. I did NOT realize the 2610 series had limitations. The 2810's don't even DO layer 3 from my understanding.

The broadcast traffic you mention is a good reason to do so. Another good reason is it will minimize the changes going into your environment. Be careful with the HP switches - not all of them are fully functional layer 3 switches. They might do hardware IP routing but the design of the routing engine is such that they are limited to 128 MAC addresses and support a limited number of static routes. HP calls the feature set "light layer 3". Examples are the ProCurve 2600 series and ProCurve 2800 series. I don't think that limit will be a problem for the branch offices - if you had a large enough environment where you had 100+ ethernet-attached devices at one or more branches you would not be asking us these questions - but it is something to keep in mind for HQ. -------------------------------------------------------------------- mail2web LIVE – Free email based on Microsoft® Exchange technology - http://link.mail2web.com/LIVE ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~
