Title : Timer Enhancements to Reduce Failover Times for the Virtual Router Redundancy Protocol for IPv4
Author(s) : R. Hott
Filename : draft-ietf-vrrp-ipv4-timers-02.txt
Pages : 19
Date : 2006-3-13
The router survivability capability provided by the Virtual
Router Redundancy Protocol for IPv4 (VRRPv4) satisfies the
requirements for many LAN environments. There are, however,
LAN environments that have sub-second failover requirements and
thus a need for finer granularity of the VRRP timers. This draft
proposes extensions to VRRPv4 [RFC 3768] for specifying sub-second
Advertisement Intervals. A new message type is introduced which
permits the timer granularity for the Advertisement Interval to
be specified. In addition, a new field is introduced permitting
the specification of the number of missed ADVERTISEMENTs before
a Virtual Router Master is declared down.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
