Step 1. Enter system view. 2. Enter interface view. 3. Enable poison reverse. Command system-view interface interface-type interface-number rip poison-reverse Remarks N/A N/A Disabled by default. Configuring the maximum number of ECMP routes Perform this task to implement load sharing over ECMP routes. To configure the maximum number of ECMP routes: Step 1. Enter system view. 2. Enter RIP view. 3. Configure the maximum number of ECMP routes. Command system-view rip [ process-id ] [ vpn-instance vpn-instance-name ] maximum load-balancing number Remarks N/A N/A Optional. 8 by default. Enabling zero field check on incoming RIPv1 messages Some fields in the RIPv1 message must be zero. These fields are called "zero fields." You can enable zero field check on received RIPv1 messages. If such a field contains a non-zero value, the RIPv1 message will not be processed. If you are certain that all messages are trustworthy, then 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: Step 1. Enter system view. 2. Enter RIP view. 3. Enable zero field check on received RIPv1 messages. Command system-view rip [ process-id ] [ vpn-instance vpn-instance-name ] checkzero Remarks N/A N/A Optional. Enabled by default. Enabling source IP address check on incoming RIP updates You can enable source IP address check on incoming RIP updates. For a message received on an Ethernet interface, RIP compares the source IP address of the message with the IP address of the interface. If they are not in the same network segment, RIP discards the message. IMPORTANT: Disable the source IP address check feature if the RIP neighbor is not directly connected. 29
