BFD for Static Routes

BFD for Static Routes

Unlike dynamic routing protocols, static routes do not have a dedicated detection mechanism. If a fault occurs, static routes cannot detect the fault and network administrators must delete the corresponding static route. BFD, on the other hand, allows for fault detection on static routes on a public network.

Each static route can be bound to a BFD session. When a BFD session bound to a static route detects a fault (for example, the link changes from Up to Down), BFD reports the fault to the routing management (RM) module. The RM then configures the route as inactive, indicating that the route is unavailable and deleted from the IP routing table.

When the BFD session bound to the static route is successfully established or the link of the static route recovers (that is, the link changes from Down to Up), BFD reports the event to the RM and the RM configures the static route as active, indicating that the route is available and added to the IP routing table.
