RIP 115
Perform the following configurations in RIP View.
Specifying the Operating State of the Interface
In the Interface View, you can specify whether RIP update packets are sent and
received on the interface. In addition, you can specify whether an interface sends
or receives RIP update packets.
Perform the following configuration in Interface View:
The
undo rip work
command and the
undo network
command have similar but
not the same functions. The
undo rip work
command allows other interfaces to
forward the route of the interface applying this command. The
undo network
command prevents other interfaces from forwarding the route of the interface
applying this command, and it appears that this interface has been removed.
In addition, the
rip work
command is functionally equivalent to both the
rip
input
and
rip output
commands.
By default, all interfaces except loopback interfaces both receive and transmit RIP
update packets.
Disabling Host Route
In some cases, the router can receive many host routes from the same segment,
and these routes are of little help in route addressing but consume a lot of
network resources. Routers can be configured to reject host routes by using the
undo host-route
command.
Perform the following configurations in RIP View.
By default, the router receives the host route.
