summary: gateway failover.

Fri Nov 13 00:29:33 UTC 1998

first of all, sorry for the duplicate message. i originally 
sent it without my proper from address to avoid having my 
primary mailbox spammed, but thought it wouldnt go through 
because the from address wasnt on nanog-post...

second, i incorrectly referred to the rfc for IRDP as 1285, 
when it is 1256. 

re: IRDP support. the following os's/routing daemons have support: 

gated (version ?) 
Solaris (in.rdisc(1))
Windows NT (with sp3) 
Windows 95 (with Sockets 2) 

a couple of useful urls were sent my way, the most interesting
being:

http://www.eddieware.org 

which details an Open Source HA project by Ericsson (very cool), 
which is unfortunately only supported under Linux for the time
being, though Solaris/FreeBSD support is slated for December. 

another from a usenix/lisa presentation with some good info is here: 

http://dilbert.dcs.it.mtu.edu/failover/

also, many suggestions were given for ways to accomplish this 
goal with network layer stuff (ospf, rip, interface aliases, 
proxy arp, etc.), though i was looking for an application layer 
solution, primarily. if you'd like details on the various 
suggestions, email me privately.
