To enable the system to select the static route with the smallest iterative depth as the active route, configure iterative depth-based static route selection.
Among static routes with the same prefix but different iterative depths, static routes with lower iterative depths are more stable. After iterative depth-based static route selection is configured, the system selects the static route with the smallest iterative depth as the active route and delivers it to the Forwarding Information Base (FIB) table. The other routes become inactive.
To prevent loops when Gateway GPRS Support Node (GGSN) services are forwarded between boards, run the ip route-static selection-rule relay-depth command to configure iterative depth-based static route selection.
The system view is displayed.
Iterative depth-based static route selection is configured.
The configuration is committed.
