ROTOCOL PERATION
RIP-1 from incorrectly receiving and processing the routes with subnet mask in
RIP-2. When an interface is running RIP-2, it can also receive RIP-1 packets.
Perform the following configuration in VLAN interface view.
Table 9 Specify RIP Version of the Interface
Operation
Specify the interface version as
RIP-1
Specify the interface version as
RIP-2
Restore the default RIP version
running on the interface
By default, the interface receives and sends RIP-1 packets. It transmits packets in
multicast mode when the interface RIP version is set to RIP-2.
Configure RIP-1 Zero Field Check of the Interface Packet
According to the RFC1058, some fields in the RIP-1 packet must be 0. When an
interface version is set to RIP-1, the zero field check must be performed on the
packet. If the value in the zero field is not zero, processing is refused. There are no
zero fields in RIP-2 packets so configuring a zero field check is invalid for RIP-2.
Perform the following configurations in RIP view.
Table 10 Configure Zero Field Check of the Interface Packet
Operation
Configure zero field check on the
RIP-1 packet
Disable zero field check on the
RIP-1 packet
By default, RIP-1 performs zero field check on the packet.
Specify the Operating State of the Interface
In the VLAN 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 VLAN interface view.
