Enabling L2Pt For A Protocol In Layer 2 Ethernet Interface View; Enabling L2Pt For A Protocol In Layer 2 Aggregate Interface View; Setting The Destination Multicast Mac Address For Tunneled Packets - H3C S6850 Series Configuration Manual

Enabling L2PT for a protocol in Layer 2 Ethernet interface
view
Restrictions and guidelines
LACP and EOAM require point-to-point transmission. If you enable L2PT on a Layer 2 Ethernet
interface for LACP or EOAM, L2PT multicasts LACP or EOAM packets out of customer-facing ports.
As a result, the transmission between two CEs is not point-to-point. To ensure point-to-point
transmission for the LACP or EOAM packets, you must configure other features (for example,
VLAN).
Procedure
1. Enter system view.
system-view
2. Enter Layer 2 Ethernet interface view.
interface interface-type interface-number
3. Enable L2PT for a protocol.
l2protocol { cdp | dldp | eoam | gvrp | lacp | lldp | mvrp | pagp | pvst | stp
| udld | vtp } tunnel dot1q
By default, L2PT is disabled for all protocols.
Enabling L2PT for a protocol in Layer 2 aggregate interface
view
1. Enter system view.
system-view
2. Enter Layer 2 aggregate interface view.

3. Enable L2PT for a protocol.
l2protocol { gvrp | mvrp | pvst | stp | vtp } tunnel dot1q
By default, L2PT is disabled for all protocols.
Setting the destination multicast MAC address for
tunneled packets
About the destination multicast MAC address for tunneled packets
The available multicast MAC addresses are 010f-e200-0003, 0100-0ccd-cdd0, 0100-0ccd-cdd1,
and 0100-0ccd-cdd2.
Restrictions and guidelines
For tunneled packets to be recognized, set the same destination multicast MAC addresses on PEs
that are connected to the same customer network.
As a best practice, set different destination multicast MAC addresses on PEs connected to different
customer networks. It prevents L2PT from sending packets of a customer network to another
customer network.
