Local Connection Establishment; Pw Types - HP MSR2000 Configuration Manual

3. Set up an AC between a PE and a CE:
Set up an AC by configuring a link layer connection (such as a PPP connection) between a PE and
a CE.
An AC can be one of the following types:
Layer 3 physical interface—Transparently forwards received packets over the bound PW. The
Layer 3 physical interface can be an Ethernet interface, or an ATM interface.
Layer 3 subinterface—Forwards packets received from the corresponding link (VLAN, ATM
VPC, ATM VCC, or FR DLCI ) to the bound PW. In this mode, VLANs are unique on a per
interface basis rather than on a global basis.
VLAN interface—Forwards packets received from the VLAN to the bound PW. In this mode,
VLANs are globally unique.
NOTE:
When VLANs are globally unique, packets with the same VLAN ID are forwarded over the PW bound
with that VLAN ID regardless of the receiving interfaces. If VLANs are unique on a per interface basis,
packets with the same VLAN ID from different interfaces can be forwarded over different PWs.
4. Bind the AC to the PW:
Bind the Layer 3 physical interface, Layer 3 subinterface, or VLAN interface to the PW, so the PE
forwards packets between the AC and the PW.

Local connection establishment

To set up a local MPLS L2VPN connection between two CEs:
1. Set up ACs:
Configure the link layer protocol to set up an AC between the PE and each CE. For more
information, see
2. Bind the two ACs:
Bind the PE's interfaces connected to the two CEs so the PE can forward packets between CEs.

PW types

MPLS L2VPN transports Layer 2 data of different data link layer protocols through PWs. A PE
encapsulates a Layer 2 packet received from an AC according to the PW type. The PW type is
determined by the AC type, as shown in
