Fig 1-8 BFD MAD detection
BFD MAD detection is achieved through BFD protocol. For BFD MAD detection function running
normally, enable BFD MAD detection function under the layer3 interface and configure MAD IP addre
ss on this interface. The difference between MAD IP address and the ordinary IP address is that MA
D IP address is bond to the member device, each member device in VSF should configured it and t
hey must belong to the same network segment.
When VSF is running normally, only the MAD IP address configured on master is effective, the
MAD IP associated with the slave device is not effective, BFD session is under the status of down.
When the VSF is split into two vsf, the mad ip address associated with the member on the new
vsf becomes effective. Through the connection line of bfd mad detection, the bfd session will be cre
ated between the two vsf to detect the multiple Active conflict.
