Configuring Bfd For Static Routes - HP 4800G Series Configuration Manual

The local-ip of the track entry must be the IP address of the specified outgoing interface and must
be on the network segment as the remote-ip.
For VRRP configuration, refer to VRRP Configuration in the System Volume.
For Track configuration, refer to Track Configuration in the System Volume.

Configuring BFD for Static Routes

A dynamic routing protocol notifies BFD of its neighbor information. BFD uses such information to
establish sessions with neighbors by sending BFD control packets. Static routing, which has no
neighbor discovery mechanism, implements BFD as follows:
BFD control packet mode
To use BFD control packets for bidirectional detection between two devices, you need to enable BFD
control packet mode for each device's static route destined to the peer.
Follow these steps to configure BFD control packet mode for static routes:
To do...
Enter system view
Enable BFD control
packet mode for static
routes
BFD echo packet mode
With BFD echo packet mode enabled for a static route, the local device sends BFD echo packets to the
peer, which loops it back to test the link in between.
Follow these steps to configure BFD echo packet mode for static routes:
To do...
Enter system view
Configure the source
address of echo
packets
Enable BFD echo
packet mode for static
routes
Use the command...
system-view
ip route-static dest-address { mask | mask-length }
interface-type interface-number next-hop-address bfd
control-packet [ preference preference-value ] [ tag
tag-value ] [ description description-text ]
ip route-static vpn-instance
s-vpn-instance-name&<1-6> dest-address { mask |
mask-length } interface-type interface-number
next-hop-address bfd control-packet [ preference
preference-value ] [ tag tag-value ] [ description
description-text ]
Use the command...
system-view
bfd echo-source-ip ip-address
ip route-static dest-address { mask | mask-length }
interface-type interface-number next-hop-address bfd
echo-packet [ preference preference-value ] [ tag
