Dynamic Routing RIP
Download as PPT, PDF•1 like•1,178 views
The document discusses dynamic routing and the Routing Information Protocol (RIP). It provides details on RIP including that it is a distance vector protocol that uses hop count as its metric. RIP routers exchange their full routing tables every 30 seconds and routers learn routes to networks that are up to 15 hops away. The document also includes configuration examples for three routers to establish RIP routing between networks and verify connectivity between the routers.

Dynamic Routing RIP
- 1. 1
- 2. Dynamic Routing 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. 2
- 3. Types of Dynamic Routing Protocols • Distance Vector Protocol • Link State Protocol • Hybrid Protocol 3
- 4. Distance Vector Protocol • Works with Bellman Ford algorithm • Periodic updates • Classful routing protocol • Full Routing tables are exchanged • Updates are through broadcast • Also known as “Routing By Rumor” • Example: RIP, IGRP 4
- 5. Link State Protocol • Works with Dijkstra algorithm • Link state updates • Classless routing protocol • Missing routes are exchanged • Updates are through multicast • Also known as “ Routing by Intelligence” • Example : OSPF, IS-IS 5
- 6. Hybrid Protocol • Works with DUAL algorithm • Link state updates • Classless routing protocol • Missing routes are exchanged • Updates are through multicast • Also known as “ Routing by Intelligence” • Example : EIGRP 6
- 7. Routing Information Protocol • Open Standard Protocol • Classful routing protocol • Updates are broadcasted via 255.255.255.255 • Administrative distance is 120 • Metric : Hop count Max Hop counts : 15 Max routers : 16 • Load Balancing of 4 equal paths • Used for small organizations 7
- 8. Rip Timers • Update timer : 30 sec – Time between consecutive updates • Invalid timer : 180 sec – Time a router waits to hear updates – The route is marked unreachable if there is no update during this interval. • Flush timer : 240 sec – Time before the invalid route is purged from the routing table • Holddown timer : 180sec – Specifies the amount of time for which the 8 information about poorer routes are ignored.

- 10. Disadvantages of RIP • More Bandwidth utilization • Doesn’t consider the bandwidth, works only with hop counts • Slow convergence • Formation of Routing loops 10
