By default, no LDP PW is
configured.
If the specified peer PE is not
directly connected, the local PE
automatically sends a targeted
hello to create an LDP session to the
peer PE and then exchanges the
PW ID FEC and PW label mapping
with the peer.
Binding an AC to a cross-connect
This task is mutually exclusive with Ethernet link aggregation. If a Layer 2 Ethernet interface has been
added to a link aggregation group, you cannot bind a service instance on the interface to a
cross-connect, and vice versa.
On the HP 11900 series, an AC is a service instance on a Layer 2 Ethernet interface.
After you bind a service instance on a Layer 2 Ethernet interface to a cross-connect, packets that are
received from the Layer 2 Ethernet interface and meet the match criteria of the service instance are
forwarded to the PW or another AC bound to the cross-connect. A service instance can match all packets,
tagged packets, or untagged packets.

Configuring PW redundancy
This task includes the following configurations:
• Create a backup PW for the primary PW.
• Specify whether to switch traffic from the backup PW to the primary PW when the primary PW
recovers, and specify the wait time for the switchover.
• Manually perform a PW switchover.
