------------------------------------------------------------------------
Anyone else out there ever tried to used split addressing mode on their
Fastpaths (option 9 in K-STAR v8)? We're trying to reconfigure from a
simpler existing setup using one subnet. Any experience/help would be
appreciated...
------------------------------------------------------------------------

We have a simple setup: 3 Fastpath 4s handling 3 appletalk zones, bridging
to a backbone ethernet. Fastpath configuration is (or would be!) done
using an atalkad daemon running on a central Sun. 

Originally everything went along swimmingly with the Fastpaths & their
associated Mac virtual IP addreses in the same subnet. Now though, we have
to split this subnet into 3 new separate subnets, and place the Fastpaths
on the main net, using the 'split addressing' mode.

On setting things up in the new configuration, we can get one Fastpath to
run apparently fine (although associated CAP v5 hosts don't seem to be able
to do NBP stuff correctly -- getzones & atlook fails), but on connecting
up a second fastpath, we had a massive broadcast storm from the latter,
resulting in mega net problems. 

Temporarily we have gone over to local configuration of the other 2
Fastpaths, and they seem to 'mostly' work in split addressing mode; the 
single daemon-controlled Fastpath remains stable. CAP seems to provide
AUFS and LWSRV services ok, but atlook and getzones fail. We need to move 
to a position that allows daemon-control of these two other Fastpaths.

Questions:
- Has anyone got a copy of their atalkatab and atalk.local files that they
  could send me, where you are using a similar split-addressing setup?
- Any problems I should know about in this setup -- eg. why would we get
  such a broadcast storm? Does split addressing *work* using atalkad?
- To experiment, I may wish to setup a second atalkad -- can I run this
  while the existing one is running (it's control is out of my hands), but
  running different atalkatab files?
- Why me? :-)

Thanks for any assistance! :-)
