Hi All,

We are proposing a peer learning mode in VRRP which will help in seamless
integration of VRRP with BFD.
We are looking forward to your comments on the draft.

>Revision:	00
>Title:		Fast failure detection using peer learning in VRRP with BFD
>Document date:	2015-06-12
>Group:		Individual Submission
>Pages:		16
>Status:         https://datatracker.ietf.org/doc/draft-nitish-vrrp-bfd/
>Htmlized:       https://tools.ietf.org/html/draft-nitish-vrrp-bfd-00
>   This draft presents an enhanced failure detection mechanism to detect
>   the failure of VRRP Master router on the LAN using a peer learning
>   mode.  Typically the VRRP protocol is able to perform the transparent
>   fail-over detection within a time period of 3 seconds with default
>   fail-over timers.  Real-time protocols (voice/video/real-time
>   transactional) require a maximum network disruption in the order of
>   150ms for traffic on the network.  A failure detection and fail-over
>   time of 150ms on conventionally configured VRRP protocol is extremely
>   aggressive and may impact the reliability and performance of the
>   network.
>   A more efficient mechanism for real-time failure detection can be
>   enabled in VRRP protocol by building a peer table, using a new VRRP
>   Advert packet type.  This will help in forming a mesh of BFD
>   sessions.  Once the BFD sessions are created, VRRP can receive faster
>   notification of failures, without the overhead of increased VRRP
>   protocol Advert messages.
>Please note that it may take a couple of minutes from the time of
>until the htmlized version and diff are available at tools.ietf.org.
