Usage Guidelines

After BFD for IPv4/IPv6 static routes and association between VRRP/VRRP6/E-Trunk and BFD are configured, deleting the BFD session may cause the association function to become ineffective. You can run the bfd session nonexistent-config-check enable command to enable the device to check whether the associated BFD session is deleted. When the associated BFD session is being deleted, the system displays a message indicating that the BFD session cannot be deleted. This function prevents the associated BFD session from being deleted incorrectly.

Example

# Disable the device from checking whether the associated BFD session is deleted.
