Advantages of Dynamic over static :There is no need to know the destination networks. Need to advertise the directly connected networks. Updates the topology changes dynamically. Administrative work is reduced Used for large organizations.Dynamic Routing

Distance Vector Protocol

Link State Protocol

Hybrid Protocol

Types of Dynamic Routing Protocols

Works with Bellman Ford algorithmPeriodic updatesClassful routing protocolFull Routing tables are exchangedUpdates are through broadcastAlso known as Routing By RumorExample: RIP, IGRPDistance Vector Protocol

Works with Dijkstra algorithmLink state updatesClassless routing protocolMissing routes are exchangedUpdates are through multicastAlso known as Routing by IntelligenceExample : OSPF, IS-ISLink State Protocol

Works with DUAL algorithmLink state updatesClassless routing protocolMissing routes are exchangedUpdates are through multicastAlso known as Routing by IntelligenceExample : EIGRPHybrid Protocol

Open Standard ProtocolClassful routing protocolUpdates are broadcasted via 255.255.255.255Administrative distance is 120Metric : Hop countMax Hop counts : 15 Max routers : 16Load Balancing of 4 equal pathsUsed for small organizationsRouting Information Protocol

Update timer : 30 secTime between consecutive updatesInvalid timer : 180 secTime a router waits to hear updatesThe route is marked unreachable if there is no update during this interval.Flush timer : 240 secTime before the invalid route is purged from the routing tableHolddown timer : 180secSpecifies the amount of time for which the information about poorer routes are ignored. Rip Timers

More Bandwidth utilizationDoesnt consider the bandwidth, works only with hop countsSlow convergenceFormation of Routing loops
