Driving School has 4 learning centres. The network of each learning centre is a LAN of its own. Network Cheap is contracted to install network connections between the learning centres. Network Cheap proposed to use RIP version 2. As the CEO of Driving School, will you accept this proposal? If you do not accept the proposal, what would you use for the routing protocol? Give your reasons.
Solution
IGRP—Interior Gateway Routing Protocol , EIGRP—Enhanced Interior Gateway Routing Protocol or OSPF V2—Open Shortest Path First came to a mind but RIP V2—Routing Information Protocol is a good choice
The characteristics of RIPv2 follow:
Distance-vector protocol.
Uses UDP port 520.
Classless protocol (support for CIDR).
Supports VLSMs.
Metric is router hop count.
Maximum hop count is 15; infinite (unreachable) routes have a metric of 16.
Periodic route updates sent every 30 seconds to multicast address 224.0.0.9.
25 routes per RIP message (24 if you use authentication).
Supports authentication.
Implements split horizon with poison reverse.
Implements triggered updates.
Subnet mask included in route entry.
Administrative distance for RIPv2 is 120.
Used in small, flat networks or at the edge of larger networks.
IGRP Converges slowly infact slower than RIP and for IGRP , OSPF or EIGRP all routers must be from Cisco Systems ( big constraint)
