(Optional) Configuring Static Route Selection Based on Iteration Depth
(Optional) Configuring Static Route Selection Based on Iteration Depth
Context
Route iteration refers to the process of finding the directly-connected outbound interface based on the next hop of a route. The iteration depth indicates the number of times the system searches for routes. A smaller number of the times indicates a smaller iteration depth.
When there are multiple static routes with the same prefix but different iteration depths, the system selects the static route with the smallest iteration depth as the active route and delivers it to the FIB table after static route selection based on iteration depth is configured. The other static routes then become inactive. A smaller iteration depth indicates a more stable route.
Procedure
Run system-view
The system view is displayed.
Run ip route-static selection-rule relay-depth
Static route selection based on iteration depth is configured.
By default, static routes are not selected based on iteration depth.
