HP FlexNetwork HSR6600 Configuration Manual page 328

Configure MPLS L3VPN FRR on PE 2 to achieve the following purposes:
•
When the link PE 2—CE 2 operates correctly, traffic from CE 1 to CE 2 goes through the path
CE 1—PE 1—PE 2—CE 2.
•
When BFD detects that the link between PE 2 and CE 2 fails, traffic from CE 1 to CE 2 goes
through the path CE 1—PE 1—PE 2—PE 3—CE 2.

Configuration procedure
1. Configure IP addresses and masks for interfaces as shown in
MPLS L3VPN. (Details not shown.)
For more information about configuring basic MPLS L3VPN, see
L3VPN."
2. Configure MPLS L3VPN FRR on PE 2:
# Configure the source IP address of BFD echo packets as 12.1.1.1.
<PE2> system-view
[PE2] bfd echo-source-ip 12.1.1.1
# Create routing policy frr, and specify the backup next hop as 3.3.3.3 for the route to
4.4.4.4/32.
