Configuring Bfd For Static Routes; Bidirectional Control Mode - HP HPE FlexNetwork 7500 series Configuration Manual

Step
6. (Optional.) Enable
periodic sending of
ARP requests to the
next hops of static
routes.
7. (Optional.)
Configure the
default preference
for static routes.
8. (Optional.) Delete all
static routes,
including the default
route.

Configuring BFD for static routes

IMPORTANT:
Enabling BFD for a flapping route could worsen the situation.
BFD provides a general-purpose, standard, medium-, and protocol-independent fast failure
detection mechanism. It can uniformly and quickly detect the failures of the bidirectional forwarding
paths between two routers for protocols, such as routing protocols and MPLS.
For more information about BFD, see High Availability Configuration Guide.

Bidirectional control mode

To use BFD bidirectional control detection between two devices, enable BFD control mode for each
device's static route destined to the peer.
To configure a static route and enable BFD control mode, use one of the following methods:
•
Specify an output interface and a direct next hop.
•
Specify an indirect next hop and a specific BFD packet source address for the static route.
To configure BFD control mode for a static route (direct next hop):
Step
1. Enter system view.
2. Configure BFD
control mode for a
static route.
To configure BFD control mode for a static route (indirect next hop):
Command
ip route-static arp-request interval interval
ip route-static default-preference
default-preference
delete [ vpn-instance vpn-instance-name ]
static-routes all
Command
system-view
•
Method 1:
ip route-static dest-address { mask-length |
mask } interface-type interface-number
next-hop-address bfd control-packet
[ preference preference ] [ tag tag-value ]
[ description text ]
•
Method 2:
ip route-static vpn-instance
s-vpn-instance-name dest-address
{ mask-length | mask } interface-type
interface-number next-hop-address bfd
control-packet [ preference preference ] [ tag
tag-value ] [ description text ]

Remarks
By default, the device does
not send ARP requests to
the next hops of static
routes.
The default setting is 60.
To delete one static route,
use the undo ip
route-static command.
Remarks
N/A
By default, BFD control
mode for a static route
is not configured.
