Disabling BFD for VRRP
If any or all VRRP sessions are disabled, the sessions are torn down. A final Admin Down control packet
is sent to all neighbors and sessions on the remote system change to the Down state (Message 3 on
page 179).

Configuring BFD for VLANs
BFD on Dell Force10 systems is a Layer 3 protocol. Therefore, BFD is used with routed VLANs. BFD on
VLANs is analogous to BFD on physical ports. If no routing protocol is enabled, and a remote system fails,
the local system does not remove the connected route until the first failed attempt to send a packet. If BFD
is enabled, the local system removes the route when it stops receiving periodic control packets from the
remote system.
