Step 6 Configure VRRP fast switchover using BFD sampling.
# Configure NPE1.

# Configure NPE2.
[NPE2] interface eth-trunk 1.1
[NPE2-Eth-Trunk1.1] vrrp vrid 10 track bfd-session session-name peer1 peer
[NPE2-Eth-Trunk1.1] vrrp vrid 10 track bfd-session session-name link1 link

[NPE2-Eth-Trunk1.1] vrrp vrid 10 track bfd-session session-name link3 link
[NPE2-Eth-Trunk1.1] vrrp vrid 10 track bfd-session session-name link4 link
[NPE2-Eth-Trunk1.1] vrrp vrid 10 track link-bfd down-number 2
[NPE2-Eth-Trunk1.1] vrrp trigger route
[NPE2-Eth-Trunk1.1] quit
After the configuration, run the display vrrp interface command on NPE1 and NPE2. The
command output shows that the mVRRP backup group is bound to one peer BFD session and
four link BFD sessions and the BFD session status 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 Eth-Trunk1.1 of NPE1 and NPE2 to implement VRRP fast switchover using
BFD sampling.
