This is a follow up on my AppleTalk routing problem.  Thanks for
those who took the time to help.  It seems that I am indeed routing
EtherTalk with no problems.  The actual problem is in the way that
the AGS/2 sources RTMP packets.  The DDP packet type field is
incorrectly set to type 2, with in the AppleTalk Phase 1 spec is
a NBP packet.  Because of this, some of my Suns running Mt. Xinu
KAShare are unable to see the world, as they are looking specifically
for an RTMP packet with the correct DDP packet type.  

The GatorBox is able to see both on the subnet it resides on, but
it's providing the correct RTMP packets.

Here's a sample of the packet contents using a Sun 4/60 running
SunOS 4.0.3 and the command "etherfind -x -apple";

lnth proto	source		destination	src port	dst port
  65  AppleTalk 0:0:89:0:9:54 -> broadcast
ff ff ff ff ff ff 00 00 89 00 09 54 80 9b ff 81
01 00 30 01 01 01 00 29 08 81 00 29 00 00 0b 01
00 48 02 00 0c 01 00 0a 01 00 47 02 00 2c 01 00

The above is the RTMP packet sourced by a GatorBox.  Note that the
first byte on line two is the DDP packet type field.  A 1 denotes
a RTMP packet, a 2 will denote a NBP packet.  Next, a RTMP packet
sourced by the AGS/2;

This bug exists in the current AGS/2 software version 8.1(14),
and 8.0(13) and 8.0(9).
