- RIPv1 is an older classful distance vector routing protocol that does not support VLSM, CIDR, or sending subnet masks in routing updates. RIPv2 enhances RIPv1 by including subnet masks and next hop addresses in updates, allowing it to support VLSM and CIDR. - Configuring RIPv2 involves using the "version 2" command and disabling automatic summarization if all subnets need to be advertised. The "debug ip rip" command can verify RIPv2 is operating correctly. - Troubleshooting RIPv2 focuses on checking configurations, links, and using commands like "show ip protocols" to verify the correct version and operation of RIPv2.
