LeaveAll timer—Controls the frequency with which the interface generates LeaveAll
messages.
BEST PRACTICE: Maintain default timer settings unless there is a compelling
reason to change the settings. Modifying timers to inappropriate values might
cause an imbalance in the operation of MVRP.
MVRP uses MRP messages to register and declare MVRP states for a switch and to inform
the switching network that a switch is leaving MVRP. These messages are communicated
as part of the PDU to communicate the state of a particular switch interface on the
switching network to the other switches in the network.
The following messages are communicated for MVRP:
Empty—VLAN information is not being declared and is not registered.
In—VLAN information is not being declared but is registered.
JoinEmpty—VLAN information is being declared but not registered.
JoinIn—VLAN information is being declared and is registered.
Leave—VLAN information that was previously registered is being withdrawn.
LeaveAll—All registrations will be de-registered. Participants that want to participate
in MVRP will need to re-register.
New—VLAN information is new and possibly not previously registered.
MVRP does not work with all spanning-tree protocols on EX Series switches. Table 223
on page 1519 shows which spanning-tree protocols are supported with MVRP for each
Junos operating system (Junos OS) Release that supports MVRP.
