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
Note
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.

Enabling and Disabling IPv6 Checksum Calculations for BFD on a Router

To enable or disable IPv6 checksum calculations globally on the router complete the following steps:

Cisco ASR 9000 Series Aggregation Services Router Routing Configuration Guide, Release 5.3.x
Enabling and Disabling IPv6 Checksum Support
Purpose
Enters BFD configuration mode.
Specifies delays in milliseconds for BFD session startup to
control flapping.
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.
