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.

2. Subnet mask included in route entry.
Administrative distance for RIPv2 is 120.
Used in small, flat networks or at the edge of larger networks.
