Configuring Bfd For Static Routes; Bfd Control Packet Mode - HP 3600 v2 series Configuration Manual

NOTE:
When you configure a static route, the static route does not take effect if you specify the next hop address
•
first and then configure it as the IP address of a local interface, such as Ethernet interface and VLAN
interface.
If you do not specify the preference when you configure a static route, the default preference will be
•
used. Reconfiguring the default preference applies only to newly created static routes.
• You can flexibly control static routes by configuring tag values and using the tag values in the routing
policy.
If the destination IP address and mask are both configured as 0.0.0.0 with the ip route-static command,
•
then the route is the default route.

Configuring BFD for static routes

Bidirectional forwarding detection (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. For more
information about BFD, see High Availability Configuration Guide.
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 has no neighbor
discovery mechanism. This section describes how static routing implements BFD.

BFD control packet mode

To use BFD control packets for bidirectional detection between two devices, you must enable BFD control
packet mode for each device's static route destined to the peer.
To configure a static route and enable BFD control packet mode for it, specify an outbound interface and
a direct next hop—BFD establishes a direct session, or specify an indirect next hop and a specific BFD
packet source address—BFD establishes an indirect session—for the static route.
Follow these steps to configure a static route with BFD control packet mode enabled (direct session):
