PurposeCommand or Action
Example:
RP/0/RSP0/CPU0:router(config-bfd)# dampening
initial-wait 30000
The value for maximum-wait should be greater than the
value for initial-wait.
The dampening values can be defined for bundle member
interfaces and for the non-bundle interfaces.

Enabling and Disabling IPv6 Checksum Support
By default, IPv6 checksum calculations on UDP packets are enabled for BFD on the router.
You can disable IPv6 checksum support for BFD on the entire router, or for a particular interface. These
sections describe about:
The command-line interface (CLI) is slightly different in BFD configuration and BFD interface
configuration. For BFD configuration, the disable keyword is not optional. Therefore, to enable BFD
configuration in that mode, you need to use the no form of the command.
