OMMANDS
The BPDU Tunnelling commands in the Command Line Interface (CLI) are listed (along with the appropriate parameters) in the
following table.
Users at different sites connected across a service-provider network need to use various Layer 2 protocols to scale their topologies to
include all remote sites, as well as the local sites. STP must run properly, and every VLAN should build a proper spanning tree that
includes the local site and all remote sites across the service-provider network.
Layer 2 protocol tunneling is a feature designed for service providers who carry traffic of multiple customers across their networks
and are required to maintain the Layer 2 protocol configurations of each customer without impacting the traffic of other customers.
Command Parameters
config bpdu_tunnel ports
[ <portlist> | all ] type [tunnel {stp|gvrp}|uplink|none]
show bpdu_tunnel
enable bpdu_tunnel
disable bpdu_tunnel
Each command is listed, in detail, in the following sections.
config bpdu_tunnel ports
Purpose
Used to configure BPDU Tunnelling type ports.
Syntax
[<portlist> | all ] type [tunnel {stp|gvrp}|uplink|none]
Description
This command is used to configure BPDU Tunnelling type ports.
When the device is operated with QinQ enabled, the DA will be
replaced by the tunnel multicast address, and the BPDU will be tagged
with the tunnel VLAN based on the QinQ VLAN configuration and the
tunnel/uplink settings.
When the device is operated without QinQ enabled, the BPDU will have
its DA replaced by the tunnel multicast address and be transmitted out
based on the VLAN configuration and the tunnel/uplink settings.
The tunnel multicast address for STP BPDU is 01-05-5d-00-00-00.
The tunnel multicast address for GVRP BPDU is 01-05-5d-00-00-21.
Parameters
ports
– Specifies the ports on which the BPDU Tunnelling will be
enabled or disabled.
type
– Specifies the type of ports.
Restrictions
Only Administrator and Operator-level users can issue this command.
Example usage:
To configure the BPDU tunnelling ports:
