mst-priority
Syntax mst-priority bridge-priority
no mst-priority
Context config>service>vpls>stp>mst-instance
Description This command specifies the bridge priority for this specific Multiple Spanning Tree Instance for this
service. The bridge-priority value reflects likelihood that the switch will be chosen as the regional
root switch (65535 represents the least likely). It is used as the highest 4 bits of the Bridge ID
included in the MSTP BPDU's generated by this bridge.
The values of the priority are only multiples of 4096 (4k). If a value is specified that is not a multiple
of 4K, the value is replaced by the closest multiple of 4K( lower than the value entered).
The no form of this command sets the bridge-priority to its default value.
Default 32768 — All instances that are created by the vlan-range command do not have explicit definition of
bridge-priority and will inherit the default value.
Parameters bridge-priority — Specifies the priority of this specific Multiple Spanning Tree Instance for this
service.
Values 0 — 65535
vlan-range
Syntax [no] vlan-range [vlan-range]
Context config>service>vpls>stp>mst-instance
Description This command specifies a range of VLANs associated with a certain MST-instance. This range
applies to all SAPs of the mVPLS.
Every VLAN range that is not assigned within any of the created mst-instance is automatically
assigned to mst-instance 0. This instance is automatically maintained by the software and cannot be
modified. Changing the VLAN range value can be performed only when the given mst-instance is
shutdown.
The no form of this command removes the vlan-range from given mst-instance.
Parameters vlan-range — The first VLAN range specifies the left-bound (i.e., minimum value) of a range of
VLANs that are associated with the mVPLS SAP. This value must be smaller than (or equal to)
the second VLAN range value. The second VLAN range specifies the right-bound (i.e.,
maximum value) of a range of VLANs that are associated with the mVPLS SAP.
