Dual Internet Routes [7:5028]
Hey all, My company has been annoyed by recent provider outages and wants to start to use dual internet routes through the same ISP BUT different pops. We are currently getting 2 Cisco 3640 routers with 128 of ram in each for possible future FULL BGP routes, although currently we would only be getting partial. My question is, does anyone have any advice or caveats about this type of configuration (from the router side and the ISP side). Any help would be much appreciated. Thanks.

Re: Dual Internet Routes [7:5028]
Why not have a second connection going to another ISP, using diverse routing on the cct? You will not have too many single points of failure, ie. the exchange, the ISP, etc. etc. You could load balance between the 2 connections and each router/cct would provide redundancy for the other. Pls. correct me if I am wrong in any way. Rashid Richard Tufaro wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]...

Re: Dual Internet Routes [7:5028]
What type of businees does your company do? Is there a reason to run BGP despite connecting to only 1 ISP? Unless you are a transit AS or something similar, you can route all of your internet traffic via static routes.

Re: Dual Internet Routes [7:5028]
My company is a pharmaceutical company that also is pushing for a large scale e-commerce presence. To my understanding the reason for running BGP on our side is because of the 2 pipes that we will have which will be running over the same carrier, but the carrier has informed us that because we are going to different POPS we would have to run partial BGP routes. This does not seem right to me. The deal is not finalized and im really pushing to go to 2 different ISP'S. For REAL redundancy. But as always if we get the so called redundancy thought there network then it will be cheaper then going with the 2 different ISP's. If we went with the 2 diff ISP's what kind of things would we be looking at? Buying our own AS, and getting independent IP space but besides that any caveats?

This will depend, in part, whether your address space is provider-independent or is part of your provider's allocation. See RFCs 1998 and 2270. In either case, the key is that you want to advertise your routes to the provider at both POPs, in a manner that lets the ISP know that all of your routes are reachable at both points, and, if possible, are to some extent load balanced. Assume that your allocation is 192.0.2.0/23, and you can split your addresses so that the western part of your network has addresses in 192.0.2.0/24 and the eastern part is in 192.0.3.0/24. A simple technique is to advertise West BorderEast Border 192.0.2.0/23 192.0.2.0/23 192.0.2.0/24 192.0.3.0/24 An alternative would be West BorderEast Border 192.0.2.0/24,MED=100 192.0.2.0/24, MED=200 192.0.3.0/24,MED=200 192.0.3.0/24, MED=100 Whatever method you use, it MUST be coordinated with your provider. As specified in RFC 1998, if you are multihomed to a single provider, and your address space is a subset of their allocation, mark your routes with the NO-EXPORT well-known community.

128 will not be enough for a full routing table within a couple months.
