[comp.protocols.appletalk] HELP NEEDED with KIP ROUTING

voh@doc.ic.ac.uk (Vincent O Ho) (10/04/88)

This is an URGENT request for help (from any quarters) with KIP routing.
We have just started a new term this week, and we are looking to provide
full connectivity in the department.  The following is a crude diagram of
our network topology.  Our localtalk is gatwayed by the KFPS-2 onto the
Student Subnet.  We used to have the FastPath connected onto the Departmental
Subnet, and we had CAP5 running fine on a 4.3bsd SUN and a 4.2bsd VAX.
The Gould acts as a gateway between the Student Subnet and the Departmental
Subnet.  Our Macs on the localtalk can telnet to any Unix hosts on the Student
Subnet.  However, they cannot reach any machines on the Departmental Subnet.
CAP no longer runs on any machine on the Departmental Subnet.  A copy of the
atalkatab file follows the diagram.  I have also tried using the atalkrd
rebroadcast daemon with no success.  I suspect there are flaws in my
routing set up.

			     [ VAX ]	     [ SUN ]

atalkatab:-

10.81	N1	129.31.81.0	CSGDOC	#DoC Departmental subnet
(also tried "10.81 H 129.31.82.99" with atalkrd running on 129.31.82.99)
(atalkrd address argument: 129.31.81.255)
10.82	N1	129.31.82.0	CSGDOC	#DoC Student subnet

10.85	N1	129.31.85.0	CSGDOC	#DoC Localtalk subnet
20.85	KC	129.31.85.1	CSGDOC	#Computer room 221
	I129.31.85.255	I129.31.82.99	#ipbroad ipname(=Gould)
	I129.31.82.99	L0		#ipdebug(=Gould) ipfile
	L0 L0 L0 L0	S0 S0		#ipother unused unused
	LX0	S0	S31		#flags ipstatic ipdynamic
	S20.85	S10.85	"CSGDOC"	#atneta atnete zonea

In the XXX.config file for the FastPath I have set the admin host and the
default route (nearest 'real' gateway) to both be 129.31.82.99.
Any advice or suggestion will be most welcome.

From article <453@gould.doc.ic.ac.uk>, by voh@doc.ic.ac.uk (Vincent O Ho):

- mentions problem with KIP routing.

We have almost exactly the same problem with telnet on our Mac's.

Here is our current network topology:

	    Vaxen   Suns    HP9000's
	      |      |         |
	      |      |         |                       Comp-Sci cable 128.100 
	-----------------------------------------------------------
				      |
				      |
				128.100.11.42 (1st ethernet board)
			      [ENCORE Multimax]
				192.9.200.42  (2nd ethernet board)
				      |
				      |                Comm-Eng cable 192.9.200
	-----------------------------------------------------------
	     |     |                        |
	     |     |                        |
	    Suns  PC's            [ Kinetics-Fastpath-3 ]
					    |
					    |
					    |          Appletalk cable
	-----------------------------------------------------------
	     |
	     |
	   Macs

The Mac's in the above diagram can talk to any Sun on the Comm-Eng cable
using telnet/ftp/aufs with no problems at all.  They cannot however
talk to the Encore or anything on the Comp-Sci cable at all.  
The Comm-Eng Suns have no problems talking to the Encore but they each needed 
a "route add" to talk properly initially.  Likewise on the Comp-Sci cable,
their Vaxen and Suns can talk to us ok but a "route add" was needed.

Two Sun's are AUFS servers, with one of them being the Kip master for
the KFPS:

The atalkatab entry for the Kip master Sun (which is on the Comm-Eng
cable having 192.9.200.1 as its IP address):

	S56.1	S55.200				#atneta atnete

Versions:  telnet 2.2
	   KIP 1/88
	   CAP 5.0
	   SunOS 3.5
	   Vax 4.3bsd (with early '88 tcp/ip from comp.bugs.4bsd.ucb-fixes)
	   Encore UMAX V (unixV31 ax.2.1.b 29JUL88 -- from uname -a)

Any help appreciated.
