IPv4 RoutingIPv4 routing and various IP addressing features are supported.

Supernetting, which increases the numberof subnets, is also supported. To subnet, you add a mask to the IP address to separate the network and hostportions of the IP address.At its most basic level, an IP address is 32-bits composed of network and host portions and represented indotted decimal format. For example, 00001010110101100101011110000011 is represented as 10.214.87.131.For more information about IP addressing, refer to RFC 791, Internet Protocol.24IPv4 Routing 547
