3. Configure the maximum
number of ECMP routes.
maximum load-balancing
number
By default, the maximum number
of RIPng ECMP routes equals the
maximum number of ECMP
routes supported by the system.
Use the
max-ecmp-num
command to configure the
maximum number of ECMP
routes supported by the system.
For more information about the
max-ecmp-num
command, see
Layer 3—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) maintain 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:

By default, RIPng GR is disabled.
Applying an IPsec profile
To protect routing information and prevent attacks, RIPng supports using an IPsec profile to
authenticate protocol packets. For more information about IPsec profiles, see Security Configuration
Guide.
Outbound RIPng packets carry the Security Parameter Index (SPI) defined in the relevant IPsec
profile. A device uses the SPI carried in a received packet to match against the configured IPsec
