# Clearing BFD Sessions

You can use the clear bfd session or clear ipv6 bfd session commands to clear one or more BFD sessions for IPv4 or IPv6 (respectively).

- Use the address keyword to indicate the IPv4 address of the destination to which the session has been established.
- Use the discriminator keyword to clear the BFD session associated with the unique system-wide identifier.
- Example 1
  host1#clear bfd session
- Example 2
  host1#clear bfd session address 10.10.5.24
