RIP (Routing Information Protocol) Version1 Vs Version2

Routing Information Protocol v1
• 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
• Exchange entire routing table for every 30 seconds

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

RIP Version 2
• Classless routing protocol
• Supports VLSM
• Auto summary can be done on every router
• Supports authentication
• Trigger updates
• Uses multicast address 224.0.0.9.

Advantages of RIP
– Easy to configure
– No design constraints
– No complexity
– Less overhead

Disadvantage of RIP
– Bandwidth utilization is very high as broadcast for every 30 second
– Works only on hop count
– Not scalable as hop count is only 15
– Slow convergence

Syntax to Configure RIP Version 1
