bpdu-tunnel dot1q
stp
Required
By configuring this
command on the port with
BPDU tunnel enabled, STP
BPDU tunnel is enabled for
the port.
Note:
z
For an Ethernet port, as STP is incompatible with STP BPDU tunnel, the two
features cannot be enabled at the same time. Before enabling STP BPDU tunnel for
a port, make sure STP is not enabled on the port.
z
For an Ethernet port, as the BPDU tunnel feature is incompatible with GVRP, the
two features cannot be enabled at the same time. Before enabling BPDU tunnel for
a port, make sure GVRP is not enabled on the port.
z
For an Ethernet port, as the BPDU tunnel feature is incompatible with NTDP, the
two features cannot be enabled at the same time. Before enabling BPDU tunnel for
a port, make sure NTDP is not enabled on the port (you can use the
undo ntdp
enable
command to disable NTDP). For information about NTDP, refer to the
Cluster part in this manual.
2.3 BPDU Tunnel Configuration Example
I. Network requirements
z
Customer 1, Customer 2, Customer 3, and Customer 4 are access devices of
customer networks.
z
Provider 1, Provider 2, and Provider 3 are access devices of the service provider
network, which are interconnected through trunk ports. They belong to VLAN 2 of
the service provider network.
z
STP BPDU tunnel is enabled on Ethernet1/0/4, Ethernet1/0/3, and Ethernet1/0/5.
STP packets from Customer 1, Customer 3 and Customer 4 can be transmitted
transparently in the service provider network.
z
BPDU tunnel is enabled on Ethernet1/0/2 to isolate BPDUs of Customer 2 from
those of the service provider network.
