Operation Manual – STP
H3C S9500 Series Routing Switches
[H3C-Ethernet3/1/3] stp disable
[H3C-Ethernet3/1/3] vlan-vpn enable
Caution:
The STP protocol must be enabled on those devices that have enabled BPDU
TUNNEL; otherwise after BPDUs of the client network enter the switch, they will not
be processed by the CPU, so their MAC addresses cannot be replaced, that is to
say, they cannot be transparently transported.
The port that has enabled VLAN-VPN must be configured as the access port; the
intermediate operator network must be configured as trunk link;
BPTU TUNNEL cannot be configured on ports that have enabled DOT1X, GVRP,
GMRP, STP and NTDP protocols.
