2. Enabling poison reverse
Poison reverse allows RIP to send routes through the interface where the routes were learned, but
the metric of these routes is always set to 16 (unreachable) to avoid routing loops between
neighbors.
To enable poison reverse:
Ste
p
Command Remarks
127. Enter system view.
system-view N/A
128. Enter interface view.
interface interface-type
interface-number
N/A
129. Enable poison reverse.
rip poison-reverse
By default, poison reverse is disabled.
1362BConfiguring the maximum number of ECMP routes
Perform this task to implement load sharing over ECMP routes.
To configure the maximum number of ECMP routes:
Ste
p
Command Remarks
130. Enter system view.
system-view N/A
131. Enter RIP view.
rip [ process-id ]
[ vpn-instance
vpn-instance-name ]
N/A
132. Configure the
maximum number
of ECMP routes.
maximum load-balancing
number
Optional.
By default, the maximum number of ECMP routes is 8.
The default maximum number depends on the device
model. For more information, see Network
Management Command Reference.
1363BEnabling zero field check on incoming RIPv1 messages
Some fields in the RIPv1 message must be set to zero. These fields are called "zero fields." You can
enable zero field check on incoming RIPv1 messages. If a zero field of a message contains a non-zero
value, RIPv1 does not process the message. If you are certain that all messages are trustworthy, disable
zero field check to save CPU resources.
This feature does not apply to RIPv2 packets, because they have no zero fields.
To enable zero field check on incoming RIPv1 messages:
Ste
p
Command Remarks
133. Enter system view.
system-view N/A
134. Enter RIP view.
rip [ process-id ] [ vpn-instance

N/A
135. Enable zero field check on
incoming RIPv1 messages.
checkzero
Optional.
By default, this function is enabled.
1364BEnabling source IP address check on incoming RIP updates
Perform this task to enable source IP address check on incoming RIP updates.
