Configure BFD on an IPv6 Interface
BFD for IPv6 interfaces is a demonstration feature on some products. For more information about feature support, see Fabric Engine and VOSS Feature Support Matrix.
About this task
Use the following procedure to enable and to configure BFD on an IPv6 interface. All interface configuration is performed at the VLAN or GigabitEthernet level.
Note
Enabling BFD on an interface does not establish a BFD session. To establish a BFD session, you must enable BFD globally and at the application level.
Procedure
Variable Definitions
The following table defines parameters for the ip bfd command.
Variable |
Value |
---|---|
{slot/port[/sub-port] [-slot/port[/sub-port]] [,...]} |
Identifies the slot and port in one of the following formats: a single slot and port (slot/port), a range of slots and ports (slot/port-slot/port), or a series of slots and ports (slot/port,slot/port,slot/port). If the platform supports channelization and the port is channelized, you must also specify the sub-port in the format slot/port/sub-port. |
enable |
Enable BFD on a port, VLAN, or loopback. |
interval <100-65335> |
Specifies the transmit interval in milliseconds. The default is 200 ms. Note:
The minimum value you can configure for the transmit interval is 100 ms. You can configure a maximum of 4 BFD sessions with the minimum value for the transmit interval. You can configure any remaining BFD sessions with a transmit interval that is greater than or equal to the 200 ms default value. |
min-rx <100-65535> |
Specifies the receive interval in milliseconds. The default is 200 ms. Note:
The minimum value you can configure for the receive interval is 100 ms. You can configure a maximum of 4 BFD sessions with the minimum value for the receive interval. You can configure any remaining BFD sessions with a receive interval that is greater than or equal to the 200 ms default value. |
multiplier <1-20> |
Specifies the multiplier used to calculate the amount of time BFD waits before declaring a receive timeout. The default is 3. Note:
If you configure the transmit interval or the receive interval as 100 ms, you must configure a value of 4 or greater for the multiplier. |
port {slot/port[/sub-port] [-slot/port[/sub-port]] [,...]} |
Identifies the slot and port in one of the following formats: a single slot and port (slot/port), a range of slots and ports (slot/port-slot/port), or a series of slots and ports (slot/port,slot/port,slot/port). If the platform supports channelization and the port is channelized, you must also specify the sub-port in the format slot/port/sub-port. |
vlan <1-4094> |
Specifies the VLAN ID. |
loopback <1-256> |
Specifies the Loopback ID. |
