Associate the RIP routing process with an interface specified by an IP address
or with an unnumbered interface, and configure RIP for the interface.
host1(config-router)#address 10.2.1.1
host1(config-router)#address 10.2.1.1 receive version 1
host1(config-router)#address 10.2.1.1 send version 2

host1(config-router)#address 10.2.1.1 authentication key 31barada
Each configuration step is optional, and includes the following:
(Optional) Specify a RIP receive version for an interface. By default, RIP
interfaces on your router receive both RIPv1 and RIPv2.
(Optional) Specify a RIP send version for an interface. By default, RIP
interfaces on your router send only RIPv1.
(Optional) Specify an authentication mode and authentication password or
key. This step is permitted only if both receive version and send version are
set to RIPv2.
(Optional) Enable RIP to advertise a default route.
