Also, you may want to set your border router (the one with the serials to your ISP) to route "per packet" as opposed to allowing the routes to cache. This will distribute the bandwidtch evenly across your T1's. If you don't, then a single high traffic session or destination can consume an uneven amount of bandwidth on one of your lines. You can ask your ISP to do this as well for incoming packets. -=Vandy=- -----Original Message----- From: Andy Dills [mailto:[email protected]] Sent: Sunday, June 29, 2003 3:02 PM To: Mary Grace Cc: [email protected] Subject: Re: Newbie network upgrade question, apologies in advance to NANOG On Sun, 29 Jun 2003, Mary Grace wrote: > So, is it still true that we do not need anything more powerful than a 4500 > or 4700 to run this system?

If you're multihomed to the same provider, I wouldn't even bother with getting an ASN and running BGP at all. I assume they are providing your IP space as well...if so, let them announce the route, and let their internal routing policy decide which circuit delivers the bits to you. Then, just configure two static default routes, to the two serial ports of your upstream. In this scenario, you're current router should be fine. Buy your router used, you're wasting your money otherwise. To answer your question directly, there is essentially no benefit to taking full routes from your provider from each location.
