Binding an E-Trunk to a BFD Session
Context
When the local device of an E-Trunk cannot promptly detect whether the remote device is faulty by sending E-Trunk packets, it can instead use the Bidirectional Fast Detection (BFD) protocol. You need to specify the remote IP address on the local device and create a BFD session to check the reachability of the route to the remote device. The E-Trunk then can detect faults reported by the BFD session and the device can handle the faults quickly.
Procedure
- Run:
system-viewThe system view is displayed.
- Run:
e-trunk e-trunk-id
The E-Trunk view is displayed.
- Run:
e-trunk track bfd-session session-name bfd-session-name
The E-Trunk is bound to a BFD session.
BFD sessions are used to quickly detect faults of links between the two E-Trunk member devices.
When a BFD session is bound to an E-Trunk, the system does not allow the bound BFD session to be deleted by default. To delete the bound BFD session, run the bfd session nonexistent-config-check disable command to disable the device from checking whether the bound BFD session is deleted.
