Re: Tier-2 reachability and multihoming

If the verticial position on the page indicates some kind of hierarchy (e.g. 2 and 3 are transit customers of 1, 7 is a transit customer of 3 and 4) then 4 has transit customers but no peering or transit. I would suggest this is not indicative of a realistic business plan in the real network.here, nodes 2 and 4 have no reachability, 1 / | 2 3 4 / \ \/ \ 5 6 7 8 now, node 7 is reachable from 2 and its lower level nodes, but what about node 4 and 8, and as a typical case, suppose nodes 4 and 8 have no multihoming whatsoever, what then?
