Configuring Ldp Pw Redundancy - HP FlexNetwork HSR6600 Configuration Manual

Configuring LDP PW redundancy

Step
1. Enter system view.
2. Enter cross-connect group
view.
3. Enter cross-connect view.
4. (Optional.) Specify the
switchover mode and set the
wait time for the switchover.
5. Configure the dual receive
feature for PW redundancy.
6. Enter cross-connect PW
view.
7. Configure a backup LDP PW
and enter backup
cross-connect PW view.
8. Return to user view.
9. Manually switch traffic to the
backup PW of the specified
PW.
Configuring interworking for a cross-connect
Interworking enables a PW to connect ACs that have different link types, including FR, HDLC,
Ethernet, and PPP. In an IPv4 interworking scenario, a PE extracts IPv4 packets from frames
received from the AC and sends the packets to the peer PE through the PW. The peer PE uses the
link protocol of the connected AC to encapsulate the IPv4 packets, and sends the packets through
the AC. This method hides the link types of ACs at the two ends.
To configure MPLS L2VPN interworking, follow these restrictions and guidelines:
•
When a CE is connected to a PE through an Ethernet or VLAN link:
On the Ethernet network or in the VLAN, the CE and PE must be the only Layer 3 network
devices.
On the PE's interface connected to the CE, use the default-nexthop command to configure
the default next hop address. This allows the PE to correctly encapsulate a link layer header
for packets destined for the CE.
− If you specify the unicast MAC address (the MAC address of the CE) or a broadcast
− If you specify the IP address of the CE as the default next hop, the PE resolves the IP
After you enable interworking for a cross-connect, the PE responds to all ARP requests
from the CE with its own MAC address. After you disable interworking on the PE, you must
