/24 work fine across the net. Smaller than that will likely be filtered in lots of places. You need an AS of your own and provider independent addresses to multihome properly. If both links go to the same provider and they're flexible you may be able to implement a bgp setup with your /29's and without an AS of your own. In the end complexity and cost of running a bgp setup will hurt a lot more than just upgrading your bandwidth. With BGP you can connect to multiple providers, and also inheret problems from all of them. > (2) are there any particular online docs that are recommended reading for > BGP? > RFC's, NANOG archives perhaps too Goto Cisco's website and dig around, they have lots of good documentation regarding most flavors of ip routing. http://www.cisco.com/en/US/products/ps6599/products_white_paper09186a00804fa120.shtml#wp4050 http://www.cisco.com/en/US/tech/tk365/tk80/tsd_technology_support_sub-protocol_home.html > what about books? > > Internet Routing Architetures by Sam Halabi. 2nd edition for $39 on amazon. > (3) the home gateway machine is a PII-350 w/ 64MB ram. is this too slow > for > > doing what i have asked about in (1)? With more memory it could in theory do what you want, but in reality BGP is not the tool to use to when you run out bandwidth on your 0.5M dsl line. /Tony -- Tony Sarendal - [EMAIL PROTECTED] IP/Unix -= The scorpion replied, "I couldn't help it, it's my nature" =-
