It works just fine with isolated networks. Just advertise the portions of the address space you are using out each EBGP connections. Overlapping this space with isolated networks falls under the category of bad mojo. Email me off-line if you need specifics on how to set this up. Only one AS number required. -------------------------------------------------------------- Daniel L.

I'm forwarding this off inet-access because there is a lot more BGP clue here. Anyone have any comments on the particular situation below, and/or regarding announcing different routes at multiple locations to multiple providers with single/many different ASNs?

Eventually, most of these will be connected with our own backbone. I need to find a way to make the transition as seemless as possible. First, it's my understanding that I can use a single ASN for the BGPpeeringat each of these networks. Am I mistaken?Yes, this is a Big Mistake(tm). One would need a unique ASN for each site, but they are only numbers, and the cost is like $500 each. Think about the implications of two different sites, fed by the same provider, both using the same ASN. Not a pretty picture. BGP hell.Could you please clarify what exactly the problem with doing this is? Many huge providers have multiple peering points that exchange routes using the same ASN for their peering routers don't they? -- Tim -------------------------------------------------- * Timothy M.
