Usage Guidelines

BFD can provide millisecond-level fault detection. It can work with IS-IS to fast detect faults on neighboring devices and instruct IS-IS to recalculate routes for correct packet forwarding. You can run the display isis ipv6 bfd interface command to check information about the interface enabled with IPv6 BFD for IS-IS.

Example

# Display information about the interface enabled with IPv6 BFD.

Item	Description
Interface	Interface enabled with IPv6 BFD for IS-IS
BFD6.State	IPv6 BFD status on the interface: enable disable To enables IPv6 BFD for IS-IS, run the ipv6 bfd all-interfaces enable (IS-IS) or isis ipv6 bfd enable command.
Min-Tx	Configured minimum interval for sending IPv6 BFD packets. To the parameters of IPv6 BFD sessions, run the ipv6 bfd all-interfaces (IS-IS) or isis ipv6 bfd command.
Min-Rx	Configured minimum interval for receiving IPv6 BFD packets. To the parameters of IPv6 BFD sessions, run the ipv6 bfd all-interfaces (IS-IS) or isis ipv6 bfd command.
Mul	Local detection multipliers of IPv6 BFD packets. To the parameters of IPv6 BFD sessions, run the ipv6 bfd all-interfaces (IS-IS) or isis ipv6 bfd command.
Total interfaces	Number of interfaces enabled with the IS-IS process
Total IPv6 bfd enabled interfaces	Number of interfaces enabled with IPv6 BFD for IS-IS
