Configure IS-IS to coordinate with the BFD
The IS-IS to coordinate with the BFD is configure to fast detect the link faults and enable the backup link for communication. The IS-IS to coordinate with the BFD can be configured in the following two methods: All interfaces enabled with the IS-IS protocol are coordinated with the BFD and the interface is specified to coordinate with the BFD.
For details about the BFD parameter information, refer to the BFD configuration manual.
Configuration Condition
Before configuring the IS-IS to coordinate with the BFD, first complete the following task:
- Configure the IP address of the interface to enable the neighboring nodes to be reachable at the network layer.
- Enable the IS-IS protocol.
