Hey Ralph, This statement is quite true. Is there an area you wish to break down more fully? For support, see the draft-ietf-ospf-abr-alt-04.txt which includes the following text: In OSPF domains the area topology is restricted so that there must be a backbone area (area 0) and all other

While I agree completely with Peter's statements, I think there may be two issues being mingled. Area 0.0.0.0, especially when there are no backbone-only routers, uses a DV-like algorithm to propagate inter-area and exterior routes. There's no use for a Dijkstra. Inside a nonzero area, the

Question about OSPF and LSA type 3 behavior. Doyle in Routing TCP/IP vol 1: When another router receives a Network Summary LSA from an ABR, it does not run the SPF algorithm. Rather it simply adds the cost of the route to the ABR and the cost included in the LSA. A route to the advertised
