Configuring L2PT
Overview
1) Upon receiving a layer 2 PDU from CE1 via the UNI port, PE1 replaces the destination
MAC address of the PDU with a special multicast MAC address (01:00:0c:cd:cd: d0) and
then sends the PDU to the ISP network via the NNI port.
2) The ISP network identifies the PDU and directly forwards it to the other end.
3) PE2 receives the PDU via its NNI port and restores the destination MAC address of the
PDU to its original destination MAC address.
With L2PT feature configured accordingly, the switch can transparently transmit the
PDUs of the following layer 2 protocols: 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).
