INTRA- AND INTERDOMAIN ROUTING
Routing inside an autonomous system is referred to as intradomain Routing inside an autonomous system is referred to as intradomain routing. Routing between autonomous systems is referred to as routing. Routing between autonomous systems is referred to as interdomain routing. interdomain routing.
In distance vector routing, the least cost route between any two nodes is In distance vector routing, the least cost route between any two nodes is the route with minimum distance. In this protocol each node maintains a the route with minimum distance. In this protocol each node maintains a vector (table) of minimum distances to every nodevector (table) of minimum distances to every node

The Routing Information Protocol (RIP) is an intradomain routing The Routing Information Protocol (RIP) is an intradomain routing protocol used inside an autonomous system. It is a very simple protocol protocol used inside an autonomous system. It is a very simple protocol based on distance vector routing. based on distance vector routing.
