Configuration Guide - IP Routing
Because the network topology is very simple, static routes can be configured to make RouterA
communicate with other Routers and the network. By binding BFD sessions to static routes,
BFD sessions can detect the link status, which provides the detection mechanism for static routes.
Configuration Roadmap
The configuration roadmap is as follows:

Data Preparation
To complete the configuration, you need the following data:

Procedure
Step 1 Configure an IP address for each interface.
The configuration details are not described here.
Step 2 Configure a BFD session between Router A and Router B.
# On Router A, configure a BFD session with Router B.
<RouterA> system-view
[RouterA] bfd
[RouterA-bfd] quit
[RouterA] bfd aa bind peer-ip 1.1.1.2
[RouterA-bfd-session-aa] discriminator local 10
[RouterA-bfd-session-aa] discriminator remote 20
[RouterA-bfd-session-aa] commit
[RouterA-bfd-session-aa] quit
# On Router B, configure a BFD session with Router A.
<RouterB> system-view
[RouterB] bfd
[RouterB-bfd] quit
[RouterB] bfd bb bind peer-ip 1.1.1.1
[RouterB-bfd-session-bb] discriminator local 20
[RouterB-bfd-session-bb] discriminator remote 10
[RouterB-bfd-session-bb] commit
[RouterB-bfd-session-bb] quit
Step 3 Configure a default static route and bind it to a BFD session.
# On Router A, configure a default static route to the external network and bind it to a BFD
session named aa.
Issue 02 (2014-09-30)
Configure a BFD session between Router A and Router B to detect the link between the
two devices.
Configure a default static route from Router A to the external network and bind the default
static route to the BFD session.

Default values of BFD parameters, including minimum intervals for sending and receiving
BFD control packets and local detection multiplier
