RIPng does not process the packets. If you are certain that all packets are trustworthy, disable the zero
field check to save CPU resources.

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:
