R3303-HP HSR6800 Routers MPLS Configuration Guide

After you configure such a binding, the device matches packets received on the Layer 2 Ethernet
port according to the service instance. Packets that match the service instance are forwarded by
the VPLS instance bound to the service instance. A service instance supports multiple types of
packet matching rules (such as matching all packets received on the port, packets carrying the
specified VLAN tags, all tagged packets, and all packets with no VLAN tags), providing a more
flexible VPLS instance access control.
Binding a Layer 3 interface to a VPLS instance
Follow these guidelines when you bind a Layer 3 to a VPLS instance:
• The router does not support binding a VPLS instance to a VLAN interface.
• A P2P enabled VPLS instance cannot be bound to a Layer 3 interface.
• Binding a VPLS instance on a Layer 3 interface disables IP related functions on the sub-interfaces of
the Layer 3 interface. For example, the sub-interfaces cannot receive ARP or IGMP packets. They
cannot forward unicast or multicast packets. After you remove the VPLS instance binding, the IP
related functions on the sub-interfaces recover.
To bind a Layer 3 interface to a VPLS instance:
Step Command Remarks
1. Enter system view.
system-view N/A
2. Enter interface view.

3. Bind the Layer 3 interface to a
VPLS instance.

By default, a Layer 3 interface is
not bound to any VPLS instance.
Binding a service instance to a VPLS instance
To bind a service instance to a VPLS instance, create the service instance on a Layer 2 Ethernet interface,
configure a packet matching rule for the service instance, and then bind the service instance to the VPLS
instance. After these configurations, packets that arrive at the Layer 2 Ethernet interface and match the
packet matching rule are forwarded through the bound VPLS instance.
Follow these guidelines when you bind a service instance to a VPLS instance:
• This feature is available only for routers with SAP-4EXP.
• A P2P enabled VPLS instance cannot be bound to a service instance.
• To ensure normal forwarding of VPN traffic, the Layer 2 Ethernet interface must allow the VLANs
that might appear in the VPN traffic. For information about VLAN configurations, see Layer 2—LAN
Switching Configuration Guide.
