RIP is a distance vector routing protocol. which was developed to provide routing in enterprise networks. RIP is considered the oldest distance vector routing protocol, which uses hop count as a routing metric. There are three versions in RIP which are RIP (default version), RIPv1 , RIPv2. RIP uses the UDP as its transport protocol, and its assigned the reserved port number 520.
But there are some drawbacks of RIP , which are as following:-
1. The Hop count cannot exceed 15, or routes will be dropped.
2. VLSM are not supported in RIP version 1
3. RIP has slow convergence
4. Send Periodic updates in every 30 seconds (Broadcast)
5. No mechanism to differentiate between internal and external(redistributed ) routes
EIGRP is a Hybrid distance routing protocol, which was develpoed by Cisco to provide routing in an enterprise network. It is a layer 3 routing protocol. By default, it uses Bandwidth and delay as a routing metric.
EIGRP is better than RIP because of some of the following properties:-
1. The Hop count limit is 255.
2. Classfull and Classless(VLSM) supported
3. Fast convergence in comparison of all other IGP protocols
4. First time full update, then triggred updates
5. Support Multicast
6. It can differentiate between internal and external routes with the help of different AD values like for internal routes AD is 90 and for external routes AD is 170.
These are the some basic difference which makes EIGRP better than RIP. But there are some other features also presents in EIGRP which is not in RIP.
Hope it will be helpful.
