while simulating some setups in GNS3, I was considering some options for how
to handle DHCP relaying with dhcpd running on two servers w/ failover
configured. It basically boiled down to hard-cofiguring either two (locally
assigned) well-known addresses for whatever servers will provide DHCP and let
those servers advertise via some IGP one of these IPs each - or devise some
multicast setup. During research, a long expired draft, http://www.eric-a-
hall.com/specs/draft-hall-lemon-bootp-multicast-relays-02.txt caught my
What's described in there pretty much seems like what I wanted - but I totally
failed to find any later version of the draft or any other information about
what happened to it :(
Has this ever been implemented? In ISC DHCP? Seems like the only thing to
add would be for dhcpd to join a configurable multicast group and listen
accordingly? If the draft really went into oblivion, is there any info as to
why this happened?
Apart from that I'm definately also interested in additional approaches besides
configuring the servers' actual and possibly changing IPs into every router.
Thanks in advance for your time and knowledge,
