Quick Steps for Configuring BFD Configuring BFD
page 20-4 OmniSwitch AOS Release 7 Network Configuration Guide June 2013
4 Optional: Configure a global receive time interval for all BFD sessions using the ip bfd receive
command. This command defines a default receive time value that is automatically applied when a BFD
session is created. For example:
-> ip bfd receive 500
5 Optional: Configure the receive time interval for a specific BFD session using the ip bfd interface
receive command. The value set with this command overrides the global receive time value configured for
the routing instance:
-> ip bfd interface bfd-vlan-101 receive 500
6 Optional: Configure a global detection time multiplier value for all BFD sessions using the ip bfd
multiplier command. For example:
-> ip bfd multiplier 5
7 Optional: Configure the BFD session detection time multiplier value using the ip bfd interface
multiplier command. For example:
-> ip bfd interface bfd-vlan-101 multiplier 5
Note. Demand mode is not supported. The default operational mode is Asynchronous with the echo func-
tion enabled. However, Static Routing and VRRP protocol support BFD in the echo-only operational
mode.
8 Optional: Configure the global BFD echo packet time interval using the ip bfd echo-interval
command. This command defines a default echo packet time value that is automatically applied when a
BFD session is created. For example:
-> ip bfd echo-interval 500
9 Optional: Configure the echo time interval for a specific BFD session using the ip bfd interface
echo-interval command. The echo time interval value set with this command overrides the global echo
time interval configured for the routing instance. For example:
-> ip bfd interface bfd-vlan-101 echo-interval 500
10 Optional: Enable the administrative status of a BFD interface using the ip bfd interface admin-state
command. For example:
-> ip bfd interface bfd-vlan-101 admin-state enable
Note. BFD parameters are not configurable once the BFD administrative status is enabled on the interface.
11 Enable the BFD protocol for the routing instance globally using the ip bfd admin-state command. For
example:
-> ip bfd admin-state enable
