Route Backup; Displaying And Maintaining A Routing Table - H3C S3100-52P Operation Manual

Operation Manual – Static Route
H3C S3100-52P Ethernet Switch
Note:
The smaller the priority value, the higher the priority.
The priority for a direct route is always 0, which you cannot change. Any other type
of routes can have their priorities manually configured.
Each static route can be configured with a different priority.

1.1.4 Route Backup

You can configure multiple routes to the same destination, expecting the one with the
highest priority to be the primary route and all the rest backup routes.
Route backup can help improve network reliability. Automatic switching can happen
between the primary route and a backup route.
Under normal circumstances, packets are forwarded through the primary route. When
the primary route goes down, the route with the highest priority among the backup
routes is selected to forward packets. When the primary route recovers, the route
selection process is performed again and the primary route is selected again to forward
packets.
