Step 1. Enter system view. Command system-view 2. Enter RIPng view. ripng [ process-id ] [ vpn-instance vpn-instance-name ] 3. Enable the zero field check on incoming RIPng packets. checkzero Remarks N/A N/A By default, this feature is enabled. Configuring the maximum number of ECMP routes Step 1. Enter system view. 2. Enter RIPng view. 3. Configure the maximum number of ECMP routes. Command system-view ripng [ process-id ] [ vpn-instance vpn-instance-name ] maximum load-balancing number Remarks N/A N/A By default, the maximum number of ECMP routes is the same as that configured in the max-ecmp-num command. For more information about the max-ecmp-num command, see IP Routing Command Reference. Configuring RIPng GR GR ensures forwarding continuity when a routing protocol restarts or an active/standby switchover occurs. Two routers are required to complete a GR process. The following are router roles in a GR process: • GR Restarter-Graceful restarting router. It must have GR capability. • GR Helper-A neighbor of the GR Restarter. It helps the GR Restarter to complete the GR process. After RIPng restarts on a router, the router must learn RIPng routes again and updates its FIB table, which causes network disconnections and route reconvergence. With the GR feature, the restarting router (known as the "GR Restarter") can notify the event to its GR capable neighbors. GR capable neighbors (known as "GR Helpers") keep their adjacencies with the router within a configurable GR interval. During this process, the FIB table of the router does not change. After the restart, the router contacts its neighbors to retrieve its FIB. By default, a RIPng-enabled device acts as the GR Helper. Perform this task on the GR Restarter. To configure GR on the GR Restarter: Step Command 1. Enter system view. system-view 2. Enable RIPng and enter RIPng ripng [ process-id ] [ vpn-instance view. vpn-instance-name ] Remarks N/A N/A 292
