On NPE1, run the shutdown command on GE 1/0/1.101 to replicate the fault between NPE1
and CE2.
[NPE1] interface gigabitethernet1/0/1.101
[NPE1-GigabitEthernet1/0/1.101] shutdown
[NPE1-GigabitEthernet1/0/1.101] quit
The command output shows that the BFD session between NPE1 and CE2 goes Down.

In this configuration example, the threshold for the number of link BFD sessions in the Down
state tracked by the mVRRP backup group is 2. That is, when two or more link BFD sessions
go Down, the mVRRP backup group performs master/backup fast switchover.
Currently, two link BFD sessions go Down, so the mVRRP backup group performs master/
backup switchover.
On NPE1:
l For the VRRP backup group with the VRID being 10, State is Initialize and Type is Admin.
l For the VRRP backup group with the VRID not being 10, State is Initialize and Type is

On NPE1, run the undo shutdown command on GE 1/0/1.100 and GE1/0/1.101 to replicate the
recovery of the fault between NPE1 and CE1 and between NPE1 and CE2.
