After the previous configurations, run the display vrrp interface command on the NPE. The
command output shows that, the allowable maximum number of the link BFD sessions in the
Down state tracked by the mVRRP backup group is 2, the mVRRP backup group is bound to
one peer BFD session and four link BFD sessions, and the status of all BFD sessions is Up.

NOTE
Since the service VRRP backup group is bound to the mVRRP backup group, it is only required to configure
the mVRRP backup group on GE 1/0/1.1 of NPE1 and NPE2 to implement VRRP fast switchover using
BFD sampling.
