Question 257

Which of the following statements about the mVRRP backup group are true? (Choose three.)

An mVRRP backup group can be bound to other service VRRP backup groups.

An mVRRP backup group cannot be bound to multiple service VRRP backup groups but can function as a service VRRP group to be bound to another mVRRP group.

After a VRRP backup group member is bound to an mVRRP backup group, the state machine of the VRRP backup group member becomes dependent. That is, the VRRP backup group member deletes the protocol timer, and no longersends or receives packets, and implements its state machine by directly copying the status of the mVRRP backup group.

A VRRP backup group member can be bound to only one mVRRP backup group.
