HP FlexNetwork HSR6600 Configuration Manual page 330

Configure OSPF to ensure connectivity between PEs, and configure MP-IBGP to exchange VPNv4
routing information between PEs.
Configure MPLS L3VPN FRR on PE 1 to achieve the following purposes:
•
When the link PE 1—PE 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 1 and PE 2 fails, traffic from CE 1 to CE 2 goes
through the path CE 1—PE 1—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 1:
# Configure BFD to test the connectivity of the LSP to 2.2.2.2/32.

[PE1] mpls bfd enable
[PE1] mpls bfd 3.3.3.3 32
# Create routing policy frr, and specify the backup next hop as 10.1.1.1 for the route to
4.4.4.4/32.
