• Use of timers to prevent routing loops
• Use of split horizon or split horizon with poison reverse
• Use of triggered updates
• Maximum hop count of 15

Difference between RIP v1 & RIP v2

 RIPv1

• A classful distance vector routing protocol
• Does not support discontiguous subnets
• Does not support VLSM
• Does not send subnet mask in routing update
• Routing updates are broadcast

RIPv2

• A classless distance vector routing protocol that is an enhancement of RIPv1’s features
• Next hop address is included in updates
• Routing updates are multicast
• The use of authentication is an option
