Quick Steps for Configuring BFD Configuring BFD
page 30-6 OmniSwitch AOS Release 6 Network Configuration Guide September 2009
To verify the global BFD configuration for the switch, use the show ip bfd-std command. For example:
-> show ip bfd-std
Version : 1,
Status : Enabled,
Transmit interval : 500,
Receive interval : 500,
Multiplier : 5,
Echo status : Enabled,
Echo interval : 500,
Mode : ECHO-ONLY,
Protocols registered : 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 30-4), 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-std status command. For example:
-> ip ospf bfd-std status enable
2 Enable BFD on specific OSPF interfaces using the ip ospf interface bfd-std command or on all OSPF
interfaces using the ip ospf bfd-std all-interfaces command. For example:
-> ip ospf bfd-std all-interfaces
-> ip ospf interface int1 bfd-std enable
3 Establish BFD sessions with all OSPF DR neighbors in full states only or with all neighbors greater
than or equal to the “2-way” state using the ip ospf interface bfd-std drs-only command or the ip ospf
interface bfd-std all-nbrs command. For example:
-> ip ospf interface int1 bfd-std drs-only
-> ip ospf interface int1 bfd-std all-nbrs
Configuring BFD Support for BGP
1 Register BGP with the BFD protocol using the ip bgp bfd-std status command. For example:
-> ip bgp bfd-std status enable
