Default routes

The default route is used when the IP destination address for an incoming packet does not exist in that system, so the packet is forwarded to the default route. The OMPROUTED server sends the default routes based on some global parameters from the Change RIP Attributes (CHGRIPA) command.

A default route, also known as the gateway of last resort, is the route used by the router when the IP destination address from a certain packet is unknown.

For IPv4, the default route is 0.0.0.0/0. The OMPROUTED server sends the default routes based on these global parameters from the Change RIP Attributes (CHGRIPA) command: Condition (COND), Accept default (ACPDFT), and Cost (COST).

For IPv6, the default route is ::/0. The OMPROUTED server sends the default routes based on these global parameters from the Change RIP Attributes (CHGRIPA) command: IPv6 Condition (IP6COND), IPv6 Accept default (IP6ACPDFT), and IPv6 Cost (IP6COST).
