Re: BGP peering question

["Ethan E. Dee" <edee () globalvision net>]

Considering the wording you use, I would include this,

'Peering' is not always necessary. If you can get an upstream provider 
to give you a pack of IP's and it is sufficient to just use them as a 
gateway instead of setting up peering that would be preferred.

If you decide you want to have multiple upstream providers or hit some 
kind of speed cap is when I would probably peer with someone else. So 
that you can keep your IP space but share it across a redundant 
connection from a different provider.

Then you need to decide if you want to be a hop between those two peers 
or if you want them to serve you only. You can change your routing so 
that both providers know of your routes but you are not sharing routes 
between the two providers.

BGP is an enormous protocol and extremely scalable so there is alot to 
consider before you even decide if you want to peer.

Because it can sometimes be a headache to setup.
