Step
9. (Optional.) Use
echo-mode BFD to detect
the connectivity to the
next hop of the primary
route.
10. Enter BGP-VPN instance
view.
11. Enter BGP-VPN IPv4

Enabling SNMP notifications for MPLS L3VPN

This feature enables MPLS L3VPN to generate SNMP notifications. The generated SNMP
notifications are sent to the SNMP module.
For more information about SNMP notifications, see Network Management and Monitoring
Configuration Guide.
To enable SNMP notifications for MPLS L3VPN:
Step
1. Enter system view.
2. Enable SNMP notifications
for MPLS L3VPN.

Displaying and maintaining MPLS L3VPN

You can soft-reset or reset BGP sessions to apply new BGP configurations. A soft reset operation
updates BGP routing information without tearing down BGP connections. A reset operation updates
BGP routing information by tearing down, and then re-establishing BGP connections. Soft reset
requires that BGP peers have route refresh capability.
Execute the following commands in user view to soft reset or reset BGP connections:
Command
primary-path-detect bfd echo
ip vpn-instance
vpn-instance-name
address-family ipv4 [ unicast ]
•
(Method 1) Enable MPLS
L3VPN FRR for the address
family:
pic
•
(Method 2) Reference a routing
policy to specify a backup next
hop for the address family:
fast-reroute route-policy
route-policy-name
Command
system-view
snmp-agent trap enable l3vpn
240
Remarks
By default, ARP is used to detect
the connectivity to the next hop.
Use this command if necessary in
VPNv4 route backup an IPv4 route.
For more information about this
command, see Layer 3—IP
Routing Command Reference.

Method 1 might result in routing
loops. Use it with caution.
By default, no routing policy is
referenced.
The apply fast-reroute
backup-nexthop command can
