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.
mst-revision
Syntax mst-revision revision-number
Context config>service>vpls>stp
Description
This command defines the MST configuration revision number. Two bridges are considered as a part
of the same MST region as soon as their configuration of MST-region name, MST-revision and
VLAN-to-instance assignment is identical.
