is in failure, the main route will hide itself and the router will choose one from the left
routes as a backup route whose precedence is higher than others’ to send data. In this
way, the switchover from the main route to the backup route is realized. When the main
route recovers, the router will restore it and re-select route. As the main route has the
highest precedence, the router will choose the main route to send data. This process is
the automatic switchover from the backup route to the main route.
1.2.3 Routes Shared between Routing Protocols
As the algorithms of various routing protocols are different, different protocols may
generate different routes, thus bringing about the problem of how to resolve the
differences when different routes are generated by different routing protocols. The
Quidway S3500 series switches can import the information of another routing protocol.
Each protocol has its own route redistribution mechanism. For details, please refer to
the description about "Importing an External Route" in the operation manual of the
corresponding routing protocol.
