- First of all, you can't make *none* of them seed routers. You *must*
- have at least one seed router on every network. According to Inside
- AppleTalk, if you come up as a non-seed router and there are no RTMPs
- on the net, then you don't route. Period. Having all routers seed
- routers is only a problem if you constantly are changing network
- numbers, which is something that shouldn't be going on anyway. I don't
- understand what you mean by "What's the point of seed routers?"
-
- Second, I am a group administrators for one of the networks that Chris
- Gressley manages here at Beckman, and I can tell you that I want *all*
- of her routers to be seed routers! If some bozo in the building
- decides to throw a Gatorbox on his net with *my* network number on his
- net and makes it a seed router, the next time we have a power failure
- I want his net to be broken, not mine.

- I don't get this. All routers are able to "seed" (i.e. give network
- configuration information to) other routers once they are up and
- running. Being able to "seed" is not what makes it a seed router; it's
- that you have the network information pre-configured that makes you a
- seed router. Having more than one seed router on a network works
- perfectly, unless you have conflicting network numbers, in which case
- your net is broken and won't work anyway.
-
- Well, it's also a problem if your routers don't do node aquisition
- correctly....
