But isn't this the *definition* of a default-free router? Maybe you mean we need to move away from the premise that you have to run default-free ("full BGP table!") to be taken seriously. (Maybe I'm just bitter because our network runs with "only" 26783 IPv4 BGP routes (and two defaults), so I cannot play with the big guys. :-) > With this ball and chain removed we can start looking at new > interdomain routing paradigms, such as an idr link state protocol > that can function in a never fully converged state.

There's lots of exciting new work about loop prevention in link-state internal routing protocols right here in the IETF - check out http://rtg.ietf.org/wg/rtgwg/ . Maybe some of this could be leveraged for a new external routing protocol. (Not that I think that it will be likely that we move from BGP to an entirely new protocol without replacing all current IDR players... but that doesn't mean you shouldn't try :-). -- Simon. _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
