Disabling BFD <strong>for</strong> VRRP<br />

If any or all VRRP sessions are disabled, <strong>the</strong> sessions are torn down. A final Admin Down control packet<br />

is sent to all neighbors and sessions on <strong>the</strong> remote system change to <strong>the</strong> Down state (Message 26 on<br />

page 607).<br />

BFD on <strong>Force10</strong> systems is a Layer 3 protocol. There<strong>for</strong>e, BFD is used with routed VLANs. BFD on<br />

VLANs is analagous to BFD on physical ports. If no routing protocol is enabled, and a remote system fails,<br />

<strong>the</strong> local system does not remove <strong>the</strong> connected route until <strong>the</strong> first failed attempt to send a packet. If BFD<br />

is enabled, <strong>the</strong> local system removes <strong>the</strong> route when it stops receiving periodic control packets from <strong>the</strong><br />

remote system.<br />
