(Optional) Configuring a BFD Group
Context
On a live network, to improve network reliability, a branch gateway connects to the headquarters using multiple links. The branch gateway needs to determine on which link an IPSec tunnel is established. You can associate IPSec with BFD so that the branch gateway controls IPSec tunnel setup or teardown according to the BFD session or BFD group status. The association ensures that only one link is available at any time, and implements redundancy control of the IPSec tunnel.
Procedure
- Run system-view
The system view is displayed.
- Run bfd-group group-name
A BFD group is created and its view is displayed.
By default, no BFD group is created.
- Run track bfd session-name
A BFD session is added to the BFD group.
To add multiple BFD sessions to a BFD group, run this command multiple times.
