Hi,
A VRRP backup group implements a master/backup VRRP switchover quickly by tracking the BFD session status. Theoretically, the switchover time is within 50 milliseconds.
To implement a fast switchover, you need to set a short BFD detection period.
Detection period = Received Detect Mult of the remote system x Max (Local RMRI, Received DMTI)
I don't find the documentation of NE09.
For NE40, the Local RMRI or Received DMTI can be set to a minimum of 3ms.

And the Detect Mult can be set to 3.

So, the minimum BFD detection period can reach 9 ms.

Hi,
What do you mean 50msec value?
