5.5 L2PT
L2PT (Layer 2 Protocol Tunneling) is a feature for service providers to transmit packets from
different customers across their ISP networks and maintain Layer 2 protocol configurations of
each customer. The supported Layer 2 protocols are STP (Spanning Tree Protocol), GVRP
(GARP VLAN Registration Protocol), CDP (Cisco Discovery Protocol), VTP (VLAN Trunking
Protocol), PAgP (Port Aggregation Protocol), UDLD (UniDirectional Link Detection) and
PVST+(Per VLAN Spanning Tree Plus).
When L2PT is enabled and the switch receives the specified Layer 2 protocol packets from the
UNI port, the switch encapsulates these packets with a special MAC address and sends them
across the service-provider network through the NNI port. The devices in the ISP network do
not process these packets but forward them as normal packets. The switch on the outbound
side of the ISP network receives these packets on its NNI port and restore their MAC address
to their original Layer 2 protocol destination MAC address.
The L2PT protocol is usually used with VLAN VPN feature. Thus the NNI ports that connecting
to the ISP network are configured as VPN Up-link ports.
