1.2.14 Specifying the Operating State of the Interface

In interface view, you can specify the operating state of RIP on the interface. For
example, whether RIP operates on the interface, namely, whether RIP update packets
are sent and received on the interface. In addition, whether an interface sends or
receives RIP update packets can be specified separately.
Perform the following configuration in interface view to specify the operating state of the
interface:
Enable the interface to run RIP
Disable the interface from running RIP
Enable the interface to receive RIP update packet
Disable the interface from receiving RIP update
packets
Enable the interface to send RIP update packet
Disable the interface from sending RIP update packet
The undo rip work command and the undo network command have similar but not all
the same functions. Neither of the two commands configures an interface to receive or
send RIP route. The difference also exists. RIP still advertises the routes of the
interface applying the undo rip work command. However, other interfaces will not
forward the routes of the interface applying the undo network command. It seems that
the interface is removed.
In addition, the rip work command is functionally equivalent to both the rip input
command and the rip output command.
By default, all interfaces, except loopback interfaces, receive and transmit RIP update
packets.

1.2.15 Setting RIP-2 Packet Authentication

RIP-1 does not support packet authentication. But when the interface runs RIP-2, the
packet authentication can be configured.
RIP-2 supports two authentication modes: Simple authentication and MD5
authentication. MD5 authentication uses two packet formats: One follows RFC1723
and the other follows the RFC2082.
The simple authentication does not ensure security. The authentication key not
encrypted is sent together with the packet, so the simple authentication cannot be
applied to the cases with high security requirements.
