Enable BFD at the OSPF Application Level
BFD for IPv6 interfaces is a demonstration feature on some products. For more information about feature support, see Fabric Engine and VOSS Feature Matrix.
About this task
BFD supports Open Shortest Path First (OSPF) for IPv4 interfaces and OSPFv3 for IPv6 interfaces.
Use the following procedure to enable BFD at the OSPF application level.
Note
Enabling BFD at the OSPF application level does not establish a BFD session. To establish a BFD session, you must enable BFD globally and at the interface level.
Procedure
Example
Switch:1>enable Switch:1#configure terminal Enter configuration commands, one per line. End with CNTL/Z. Switch:1(config)#interface gigabitethernet 1/3 Switch:1(config-if)#ip ospf bfd
Variable Definitions
The following table defines parameters for the ip ospf bfd command.
Variable | Value |
---|---|
{slot/port[/sub-port][-slot/port[/sub-port]][,...][slot/all][all]} |
Identifies the
slot and port in one of the following formats:
|
<1-4059> |
Specifies the VLAN ID in the range of 1 to 4059. By default, VLAN IDs 1 to 4059 are configurable and the system reserves VLAN IDs 4060 to 4094 for internal use. On switches that support the vrf-scaling and spbm-config-mode boot configuration flags, if you enable these flags, the system also reserves VLAN IDs 3500 to 3998. VLAN ID 1 is the default VLAN and you cannot create or delete VLAN ID 1. |
