Configuring BFD Quick Steps for Configuring BFD
OmniSwitch AOS Release 7 Network Configuration Guide June 2013 page 20-5
Note. Optional. Verify the BFD interface session status and configuration using the show ip bfd inter-
faces command. For example:
-> show ip bfd interfaces one
Interface Name = one,
Interface IP Address = 100.1.1.1,
Admin Status = Enabled,
Desired Transmit Interval = 300,
Minimum Receive Interval = 300,
Detection Time Multiplier = 3,
Minimum Echo Receive Interval = 300,
Authentication Present = No,
Oper Status = UP
To verify the global BFD configuration for the switch, use the show ip bfd command. For example:
-> show ip bfd
BFD Version Number = 1,
Admin Status = Enabled,
Desired Tranmit Interval = 300,
Minimum Receive Interval = 300,
Detection Time Multiplier = 3,
Minimum Echo Receive Interval = 300,
Applications Registered = STATIC-ROUTING OSPF
See the “BFD Commands” chapter in the OmniSwitch CLI Reference Guide for information about the

Quick Steps for Configuring BFD Support for Layer 3 Protocols
BFD runs on top of Layer 3 protocol traffic that is forwarded between two systems. This implementation
of BFD supports the following protocols:
• BGP
• OSPF
• VRRP Tracking
• Static routes
Once the BFD configuration is in place (see “Quick Steps for Configuring BFD” on page 20-3), the steps
described in the following sections are used to configure BFD interaction with the supported Layer 3
protocols.
Configuring BFD Support for OSPF
1 Register OSPF with the BFD protocol using the ip ospf bfd-state command. For example:
-> ip ospf bfd-state enable
2 Enable BFD session on specific OSPF interface using the ip ospf interface bfd-state command or on
all OSPF interfaces using the ip ospf bfd-state all-interfaces command. For example:
-> ip ospf interface int1 bfd-state enable
-> ip ospf bfd-state all-interfaces
