The consenous seems to be that gated is needed if your
connectivity peers require or your host needs to route
for additional networks.

Here are some of the comments I received:

From: Timothy G. Smith - Special Projects <tgsmith@Sun.COM>

Whether you need gated or not depends on your setup. If you only have
a single host connected to milnet than you should not have to run
gated (although it would probably be a good idea to do so anyway).

If you have a network of hosts talking to milnet than you need to use

gated allows you to tell milnet that you have some networks connected
"behind" your milnet machine. The hosts on milnet have to be able to
find a route to your network; without using something to speak EGP or
BGP to the milnet there is no way for you to tell the hosts on milnet
about your network.

Gated is included on the Sunlink X.25 7.0 distribution.

You don't need to use gated, unless the way your network works requires
you to use gated! The net distributes routing information using fixed
protocols. If you don't support them, they can't support you.

   gated supports both EGP and BGP as well as RIP and Hello.

   You can get gated via anonymous ftp from I am running
version 2.1 (3.0 is a beta version). The O'Reilly book "TCP/IP Network
Administration" gives the nitty-gritty on gated as well as many other
network problems. I highly recommend it.

  I use gated because I have to talk EGP to a leaf router on the internet,
  we have Sunlink HSIS/INR for a Sun that acts as router for a net off
  the internet. Routed will not acquire the routes or build the routing
  tables that [EB]GP will; it is also just plain not good to run routed.

  But it wouldn't be necessary run [E|B]GP if your machine is not a router
  or you have only one possible route to the next hop. It is best to use
  static routes in this case - just set the router to be the default

Gated will give you egp, bgp, and good control of RIP in complex
situations. Also makes handling of static and preferred routes
easy. You can get egp and bgp separately but then they won't
be as well integrated with interior routing.

It is a good tool. Well worth your time on any host that is
multiply connected or acting as a border router. I suggest you
get a copy by anon ftp from and examine the
docs and (plethora of) README files.
