Configuring Rip-1 Zero Field Check Of The Interface Packet; Specifying The Operating State Of The Interface - 3Com 8800 Configuration Manual

3Com Switch 8800 Configuration Guide
always become unreachable at the point when a new period starts, the actual value of
Garbage-collection timer is three to four times that of Period Update timer.
Note:
You must consider network performance when adjusting RIP timers, and configure all
the routers that are running RIP, so as to avoid unnecessary traffic or network jitter.

18.2.13 Configuring RIP-1 Zero Field Check of the Interface Packet

According to the RFC1058, some fields in the RIP-1 packet must be 0, and they are
called zero fields. Therefore, when an interface version is set as RIP-1, the zero field
check should be performed on the packet. But if the value in the zero filed is not zero,
processing will be refused. As there is no zero field in the RIP-2 packet, this
configuration is invalid for RIP-2.
Perform the following configuration in RIP view.
Table 18-14 Configure zero field check of the interface packet
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.

18.2.14 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.
Table 18-15 Specify the operating state of the interface
Enable the interface to run RIP
Disable the interface to run RIP
Enable the interface to receive RIP update packet
Disable the interface to receive RIP update packet
