# Set Ethernet 3/1/3 to a trunk port and add this port to all the VLANs.

[H3C] interface Ethernet3/1/3

[H3C-Ethernet3/1/3] port link-type trunk

[H3C-Ethernet3/1/3] port trunk permit vlan all

Caution:

STP must be enabled on VLAN-VPN tunneling-enabled devices; otherwise BPDUs

in the customer network cannot be transmitted transparently.

VLAN-VPN-enabled ports must be configured to Access ports. The link type of the

intermediate service provider network must be configured to the Trunk link.

VLAN-VPN tunneling is unavailable to ports with any of the protocols among 802.1x,

GVRP, STP, network topology discovery protocol (NTDP), and GARP multicast

registration protocol (GMRP) enabled.
