VLAN Routing OSPF Configuration For larger networks Open Shortest Path First (OSPF) is generally used in preference to RIP. OSPF offers several benefits to the administrator of a large and/or complex network: • Less network traffic: - Routing table updates are sent only when a change has occurred - Only the part of the table which has changed is sent - Updates are sent to a multicast, not a broadcast, address • Hierarchical management, allowing the network to be subdivided The top level of the hierarchy of an OSPF network is known as an autonomous system (AS) or routing domain, and is a collection of networks with a common administration and routing strategy. The AS is divided into areas: intra-area routing is used when a source and destination address are in the same area, and inter-area routing across an OSPF backbone is used when they are not. An inter-area router communicates with border routers in each of the areas to which it provides connectivity. The 7000 Series Managed Switch operating as a router and running OSPF will determine the best route using the assigned cost and the type of the OSPF route. The order for choosing a route if more than one type of route exists is as follows: - Intra-area - Inter-area - External type 1: the route is external to the AS - External Type 2: the route was learned from other protocols such as RIP OSPF v1.0, June 2010 6-35
