Gated supports RIP as described in the UNIX routed man page (with some HELLO-like extensions), HELLO (formal specs, RFC 891); Beware that the HELLO in gated has changed to parallel the NSFNet fuzzballs, so RFC 891 is out of date. Gated also supports EGP (kirton's EGP). EGP (formal specs, RFC 904, Kirton's EGP under UNIX, RFC 911) Mark

EGP (formal specs, > RFC 904, Kirton's EGP under UNIX, RFC 911) This looks like it's just the sort of thing one would want in a gateway Sun system. Can anyone tell me where I can get the code for 'gated'? I can FTP if necessary. T i A, -- David S.

Sun systems can only act as gateways between networks of the same class and subnet mask. Maybe a Sun could gateway between a class C non-subnetted network and a class B network with subnetmask == 255.255.255.0. Phil Wood (cpw@lanl.gov)

We use SUN-3's as gateways between class-B and class-C nets, and they seem to work just fine. There -is- a restriction that only one network can be subnetted (can gateway among subnets of a single net, can gateway also onto class A/B/C non-subnetted nets, but cannot gateway between subnets of two different nets). This is true under SUN 3.3 at least.

< in reference to Sun's as gateways > I know for sure that they only have one place in memory for a subnet mask. Maybe, if you do not subnet, things work. I also know that we have to trash (logically, for the indefinite future) the IPC boards from Sun. We have a class B subnetted with 6 bits for net and 10 for host. I know that's a strange way to subnet. But, hey, that's the way DEC does it! We also have a Class C subnetted with 3 bits for subnet and 5 bits for host (now thats more like it). It cuts down on the plethora of broadcasts/arps/rarps/ICMP-Redirects/ICMP-Mask-replys from every host known to man, when ONE Sun client boots! Oh, oh. I'm beginning to feel stressed! Is this time for a flame on banner? No, I must maintain some kind of decorum. I'll just cut the remainder of this message, and save it for later. Actually, its pretty good ..., nah. One does have a choice though, there are other's out there that make real IP routers. Phil Wood cpw@lanl.gov

To clarify: Suns running version 3.3 or later of the Sun Operating System can in fact route packets between class A, B, C, or any combination thereof. There is only ONE subnet mask possible in the 3.X series of releases, so if you are routing between two subnetted networks of any class, the subnet masks must be the same. Routing between a subnetted network and a non-subnetted net is never a problem, and the entire restriction will dissappear in release 4.0, which uses the 4.3 subnetting code.
