The static route is a special route manually configured by the network administrator for a specified path. Different from a dynamic route, the static route does not have any detection mechanism. When a fault occurs on the network, the network administrator needs to detect and locate the fault.
By means of interworking between BFD sessions and the static route, the static route is bound with static BFD sessions, so that the static route state is updated in pace with the BFD session state.
BFD sessions can be established between devices to improve the network reliability and accelerate route convergence upon network failures. The status of links between devices can be monitored using BFD sessions.
Key configurations for the interworking between BFD sessions and the static route on the USG firewall are as follows:
1. # Configure BFD sessions for USG_B.
[USG_A] bfd ab bind peer-ip 10.1.1.2
[USG_A-bfd-session-ab] discriminator local 10
[USG_A-bfd-session-ab] discriminator remote 20
2. # Configure the interworking between the static route and BFD sessions.
[USG_A] ip route-static 192.168.1.0 255.255.255.0 10.1.1.2 track bfd-session ab
Note: The USG6000 configuration must be consistent with the key configuration of the USG2000&5000. This case takes the USG2000&5000 as an example to describe the configuration. You can learn the USG6000 configuration in other configurations.
