ipv6 ospf bfd

Enables Bidirectional Forwarding Detection (BFD) sessions and configures BFD session parameters for an Open Shortest Path First Version 3 (OSPFv3) interface.
Syntax
ipv6 ospf bfd [ disable | min-tx transmit-time min-rx receive-time multiplier number | passive ]
no ipv6 ospf bfd [ disable | min-tx transmit-time min-rx receive-time multiplier number | passive ]
Command Default

BFD is not configured for OSPFv3.

Parameters
disable
Disables BFD on the interface.
min-txtransmit-time
Specifies the interval, in milliseconds, a device waits to send control packets to BFD peers. Valid values range from 50 through 50000 milliseconds. The default is 300.
min-rxreceive-time
Specifies the interval, in milliseconds, a device waits to receive control packets from BFD peers. Valid values range from 50 through 50000 milliseconds. The default is 300.
multipliernumber
Specifies the number of consecutive BFD control packets that must be missed from a BFD peer before BFD determines that the connection to that peer is down. Valid values range from 2 through 50. The default is 3.
passive
Specifies that the BFD session operates in passive mode.
Modes

Interface subtype configuration mode

Usage Guidelines

Using this command overrides global settings configured using the bfd command in OSPFv3 router configuration mode.

It is recommended to use the default values.

This command is supported for ICX 7850 devices only.

The no form of the command disables BFD sessions on the interface.

The no ipv6 ospf bfdmin-txtransmit-timemin-rxreceive-timemultipliernumber command removes configured BFD session parameters and restores the default parameters.

The no ipv6 ospf bfd passive command removes BFD from the OSPFv3 interface. To unconfigure passive mode for the interface, use the ipv6 ospf bfd command.

Examples

The following example enables BFD for an OSPFv3-enabled Ethernet interface. The default BFD session timer values are applied. 

device# configure terminal 
device(config)# interface ethernet 1/1/1
device(config-if-e40000-1/1/1)# ip address 10.0.0.2/24
device(config-if-e40000-1/1/1)# ipv6 ospf bfd

The following example enables BFD for an OSPFv3-enabled Ethernet interface and sets specific BFD session timer values. 

device# configure terminal 
device(config)# interface ethernet 1/1/1
device(config-if-e40000-1/1/1)# ip address 10.0.0.2/24
device(config-if-e40000-1/1/1)# ipv6 ospf bfd
device(config-if-e40000-1/1/1)# ipv6 ospf bfd min-tx 280 min-rx 280 multiplier 4

The following example enables BFD for an OSPFv3-enabled Ethernet interface and sets the BFD session to passive. 

device# configure terminal 
device(config)# interface ethernet 1/1/1
device(config-if-e40000-1/1/1)# ipv6 enable
device(config-if-e40000-1/1/1)# ipv6 ospf bfd
device(config-if-e40000-1/1/1)# ipv6 ospf bfd passive

The following example disables BFD for an OSPFv3-enabled Ethernet interface if it has been enabled. 

device# configure terminal 
device(config)# interface ethernet 1/1/1
device(config-if-e40000-1/1/1)# ipv6 ospf bfd disable
