Restrictions And Guidelines For Mpls L2Vpn; Mpls L2Vpn Configuration Task List - HP FlexNetwork 10500 Series Configuration Manual

Restrictions and guidelines for MPLS L2VPN

Follow these restrictions and guidelines when you configure MPLS L2VPN:
•
On a PE, the interfaces connected to CEs do not support STP. Make sure the interfaces do not
form loops. For more information about STP, see Layer 2—LAN Switching Configuration Guide.
•
On a PE, the interface where the public tunnel for a PW is established cannot be a Layer 3
Ethernet subinterface or Layer 3 aggregate subinterface.
•
Do not configure EVB on an interface that has been configured with an Ethernet service
instance. For more information about EVB, see EVB Configuration Guide.
•
The device does not support assigning an AC to a port isolation group.
•
MPLS L2VPN is mutually exclusive with EVI and VXLAN. For more information about EVI and
VXLAN, see EVI Configuration Guide and VXLAN Configuration Guide.

MPLS L2VPN configuration task list

To establish an MPLS L2VPN, you must perform the following tasks:
1. Configure an IGP to achieve IP connectivity within the backbone.
2. Configure basic MPLS, LDP, or MPLS TE to set up public tunnels across the backbone.
3. Configure MPLS L2VPN on the PEs, including setting up PWs, and binding ACs to PWs.
This chapter only describes MPLS L2VPN configurations on the PEs.
MPLS L2VPN configurations vary by scenario:
•
Remote connection—To create a remote connection, configure an AC, configure a PW in
cross-connect view or auto-discovery cross-connect view, and bind the AC to the PW in
cross-connect view or auto-discovery cross-connect view.
•
Multi-segment PW—To create a multi-segment PW, configure two PWs and bind the two PWs
in cross-connect view.
To configure MPLS L2VPN on a PE:
