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
mst-max-hops
Syntax mst-max-hops hops-count
no mst-max-hops
Context config>service>vpls>stp
Description
This command specifies the number of hops in the region before BPDU is discarded and the
information held for the port is aged out. The root bridge of the instance sends a BPDU (or M-record)
with remaining-hop-count set to configured <max-hops>. When a bridge receives the BPDU (or M-
record), it decrements the received remaining-hop-count by 1 and propagates it in BPDU (or M-
record) it generates.
The no form of this command sets the hops-count to its default value.
Default
20
Parameters
hops-count — Specifies the maximum number of hops.
mst-name
Syntax mst-name region-name
no mst-name
Context config>service>vpls>stp
Description This command defines an MST region name. Two bridges are considered as a part of the same MST
region as soon as their configuration of the MST region name, the MST-revision and VLAN-to-
instance assignment is identical.
The no form of this command removes region-name from the configuration.
Default
no mst-name
Parameters region-name — Specifies an MST-region name up to 32 characters in length.

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.
Values
1 to 4094 — 1 to 4094
Values
1 — 40
