Routing Information Protocol (RIP)
When the router or switch runs RIP, it receives routing information from
neighbouring routers, and can advertise RIP, statically-configured and
interface routes to neighbouring routers. You can filter routing information at
the processing points shown in the following figure.
Interface Routes
When you create an interface on the router or switch, it automatically creates
an interface route. This route tells the router or switch to send packets over that
interface when the packets are addressed to the interface’s subnet.
Various routing protocols automatically import and advertise interface routes.
For BGP, you can filter interface routes when the protocol imports them, as
shown in the following figure.
