Static routing-Track-BFD collaboration configuration example
Network requirements
As shown in
Router A is the default gateway of the hosts in network 20.1.1.0/24.
•
Router B is the default gateway of the hosts in network 30.1.1.0/24.
•
•
Hosts in the two networks communicate with each other through static routes.
To ensure network availability, configure route backup and static routing-Track-BFD collaboration on
Router A and Router B as follows:
•
On Router A, assign a higher priority to the static route to 30.1.1.0/24 with the next hop Router B.
This route is the master route. The static route to 30.1.1.0/24 with the next hop Router C acts as the
backup route. When the master route is unavailable, BFD can quickly detect the route failure to
make the backup route take effect.
On Router B, assign a higher priority to the static route to 20.1.1.0/24 with the next hop Router A.
•
This route is the master route. The static route to 20.1.1.0/24 with the next hop Router C acts as the
backup route. When the master route is unavailable, BFD can quickly detect the route failure to
make the backup route take effect.
