Here's comment text taken out of the atalkd.conf file for
netatalk-1.4.99-0.20001108mdk:
# -seed only works if you have multi-interfaces. Any missing arguments are
# automatically configured from the network. Note: lines can't actually be
# split, tho it's a good idea.
#
# -router is like -seed but it allows single-interface routing. -dontroute
# disables routing for the specified interface.
#
Basically, here's why you would want to perform "routing" on a single
interface. Say you have multiple macs on one single subnet, but there's
enough appletalk devices (printers, servers, clients, etc) broadcasting
appletalk services to clutter your chooser. You could define multiple
zones in a single subnet and have different devices broadcast in different
zones accordingly.
this is especially handy if you have printer spoolers set up for your
printers, but don't want to "hide" the actual printer for specific reasons.
with this method you could broadcast the actual printer in a zone ("Real
Printer Zone" for example) and broadcast the spoolers in a different zone
("Print Spooler Zone" for another example) ... this cleans up the chooser
really nicely. (as well, can be done for AFP services)
you should read this: http://www.neon.com/atalk_routing.html for more
detailed information regarding appletalk routing.
