See also Shortest Path Algorithm (Networking), RIP.

RIPv2
• Interior gateway protocol (so within an Autonomous System )
• Distant Vector routing protocol
• Supports subnetting and CIDR addressing
• Including Variable Length subnet masking (VLSM)
• Cost Metric
• Hop count only
• 15 is maximum hop count (so 16 = infinity)
• Updates
• Sent every 30 seconds
• Also triggered by changes
