This packet forwarding process is not applicable to the CCC mode of MPLS L2VPN. For more information
about the CCC mode of MPLS L2VPN, see "CCC MPLS L2VPN."
Local connection operation
Local connection establishment
To set up a local MPLS L2VPN connection between two CEs:
1. Set up ACs:
Configure the link layer protocol on the PE and a connected CE to set up a link layer connection
(such as a PPP connection) between the PE and the CE.
2. Bind the two ACs that connect the two CEs:
You can bind the ACs by binding the PE's Layer 3 interfaces connected to the two CEs. After the
binding, the PE forward packets received from one AC to another.
Packet forwarding process
As shown in Figure 38, MPLS L2VPN forwards Layer 2 packets received from CE 1 directly to CE 2.

Implementation of MPLS L2VPN
To establish a local connection, you only need to bind the two ACs on the PE. (Details not shown.)
This section only describes how to set up a remote MPLS L2VPN connection in different modes.
CCC MPLS L2VPN
The CCC mode sets up a CCC connection by establishing two static LSPs in opposite directions and
binding the static LSPs to ACs.
