Re: Where is the edge of the Internet?
$author = "alok" ; > > do most SPs/IXs actually have the entire BGP routing table with them? how longs that piece of string? there are many ways to design a network. you can have no BGP feeds (defaults + static), you can have no full BGP feeds (maybe "customer only" feed across a peering circuit + defaults), a full house of BGP feeds (different views from multiple providers / peers) or some other variation on these themes (for large quantities of variations). you don't need every router carrying the entire table either, you can structure the network so that a subset of routers carry whatever counts as your "full table". > so that every network in the world which is registered is availble to them > in some form or another? you either run with a default (which fills in any gaps in the routing table) or defaultless (where you need a full table). you can run both (default free core, defaults at the edges). just depends on what BGP views you have and how you structure your network. marty -- So stay tonight.
