Volume 4-Layer 3 Configurations / Chapter 27-Routing Information Protocol Next Generation (RIPng) Chapter Overview • RIPv2 allows attaching arbitrary tags to routes, RIPng does not. • RIPv2 encodes the next-hop into each route entries; RIPng requires specific encoding of the next hop for a set of route entries. Architecture RIPng routers communicate the sets of destinations they can reach with each other and also the next hop address to which data should be sent in order to reach those destinations. This contrasts with link-state IGPs; vectoring protocols exchange routes with one another, whereas link state routers exchange topology information, and calculate their own routes locally. A vector routing protocol floods reach-ability information throughout all routers participating in the protocol. By flooding reach-ability information, every router has a routing table containing the complete set of destinations known to the participating routers. The block diagram below shows the architecture of the RIPng stack. Route Store • tracks all routes stored • implements the soft state mechanism for timing out old routes • calculates the updates needed to keep in synchronization with all changes to active routes • provides the RIP Route MIB for querying the routes in the RIPng routing table DGS-6600 Configuration Guide 262
