4.6.3 Binding the Service VRRP Backup Group to the mVRRP
Backup Group
Through the bindings between member VRRP backup groups and the mVRRP backup group,
the state machines of member VRRP backup groups can be consistent with the state machine of
the mVRRP backup group.
Context
Do as follows on the device that need perform VRRP fast switchover:
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
interface
The view of the interface where the service VRRP backup group is configured is displayed.
Step 3 Run:
vrrp vrid
number vrid virtual-router-id2
The service VRRP backup group is bound to the mVRRP backup group.
After the binding, the state machine of the service VRRP backup group becomes dependent.
That is, the service VRRP backup group deletes the protocol timer and stops sending or receiving
VRRP packets. Alternatively, it implements its state machine by directly copying the status of
the mVRRP back group. A service VRRP backup group can be bound to only one mVRRP
backup group.
Only a single member VRRP backup group can be configured on a single interface.

4.6.4 Configuring an mVRRP Backup Group to Track the BFD
Session Status
By tracking the status of a BFD session, a VRRP backup group can perform the fast VRRP
switchover when the BFD session status changes.
Context
Do as follows on a router that needs the fast VRRP switchover:
