Configuring Mpls L3Vpn Frr - HP MSR2000 Configuration Manual

Step
2. Enable SNMP notifications for
MPLS L3VPN.

Configuring MPLS L3VPN FRR

There are two methods to configure MPLS L3VPN FRR:
• Method 1—Execute the pic command in BGP-VPN IPv4 unicast address family view. The device
calculates a backup next hop for a BGP route in the VPN instance if there are two or more
unequal-cost routes to reach the destination.
• Method 2—Execute the fast-reroute route-policy command in BGP-VPN IPv4 unicast address family
view to reference a routing policy in which a backup next hop is specified by using the command
apply [ ipv6 ] fast-reroute backup-nexthop. The backup next hop calculated by the device must be
the same as the specified backup next hop. Otherwise, the device does not generate a backup next
hop for the primary route. You can also configure if-match clauses in the routing policy to identify
the routes protected by FRR.
If both methods are configured, Method 2 takes precedence over Method 1.
To configure MPLS L3VPN FRR:
Step
1. Enter system view.
2. Enable MPLS BFD.
3. Configure the source IP
address
packets.

The mpls bfd enable command
applies to VPNv4 route backup for a
VPNv4 route and IPv4 route backup
for a VPNv4 route. For more
information about this command,
see MPLS Command Reference.
The bfd echo-source-ip command is
required when echo-mode BFD is
used to detect primary route
connectivity in VPNv4 route backup
for an IPv4 route. For more
information about this command,
see High Availability Command
Reference.
