     Hi all.

     1  I have and AGS+ on one end, a leased line, and an IGS on the 
        other with Ethernets at both end sites.  In addition I have 
        a parallel 3270 over serial SNA leased line.  This seems just 
        a bit silly.  Is there any way I can piggy-back/schlep the SNA 
        between my IGS and AGS+, split it back out and dump that 3270
        leased line? 

     2  I have an IBM running applications that use 3270 over SNA.  None 
        of them are written to use 3270 over TCP/IP (dumb move not 
        writing the applications I/O independent but then I didn't
        write any of them).  I know cisco makes an x.25 to TCP/IP
        protocol translator.  Do they also do anything similar for 
        TCP/IP and SNA.  

     I realize that these are probably best asked of my sales rep.  
Believe it or not it's very often easier and much faster asking here 
than finding my sales rep.  He's out selling.

     Thanks much.

Subject: split horizon with redistributed routes
Date: 27 Aug 92 07:21:38 GMT
Organization: Stanford Linear Accelerator Center

I have a network with several ciscos on it:

      |            |            |
      +---- R1 ----+            |
      |            +---- R2 ----+
      |            |            |

    net A       net B        net C

The routers speak IGRP amongst themselves, and redistribute IGRP into
RIP for the benefit of hosts which don't understand anything else.
(The network is actually rather more complicated; I'm simplifying to
illustrate the problem.)  Another router on net A is a gateway to the
Internet, which R1 and R2 learn about via IGRP and then redistribute
to RIP as default routes.

The problem is that R2 advertises a default route on net B, and then
sends redirects to anybody who uses it.  I understand that the usual
split horizon rules don't apply here since R2 learned the route via
net B but not from the same protocol, but I'd like to apply split
horizon just the same.  That is, if R2 learned a route (default in
this example, but it holds for any route) via net B, I don't want it
to advertise it on net B.  Period.

Can I do this?  Static filters aren't acceptable, and I can't just run
RIP because the networks are not homogenous and I want the routers to
use the "best" route available.

I am running OS8.3(3) due to the ARP bridging problems that are being discussed.  (BTW it seemed to be related to SNAP encap and wasnt' there under DIX). 

I keep seeing these ARP packets being sent out on ethernet interfaces that show type 6 (802.5 token ring).  Although the hardware and protocol address lengths are correct and every one on the network seems to be able to talk together just fine, I wonder if identifying the interface as token ring limits transmission speed on the network some how to 4MB vs 10MB.  I've seen Type 1 ARP packets but they seem to be bridged from another network interface.

I would second that, wholeheartedly. As I write this, we're up to 56 Xyplex

no trouble with them, and when we have, Xyplex Technical Support has been

Sorry, if this is a simple question, but we are new to Cisco.    
Please reply to alan@bofa.com. I will post replies if appropriate.

We have an AGS+, version 9.0(1).  We have configured a token ring interface
with a secondary address. This address is primarily composed of a network
of Sun work stations.

All the Sun Workstations on the network can ping the router and telnet into it,
and a "show ip route" on the router displays the network as being Connected.  Also
the arp table shows the correct MAC level address of any sun who pings or telnets
to the router.  The problem is that the Router can not ping the Suns or telnet 
into any of the sun hosts.  

I don't understand why this should be the case.


Thanks.

Nope, you can't have different-length masks on the same "real" network number.
(I think this is scheduled to change, sometime in the not-too-distant future.)
However, you can get around the problem by using "ip unnumbered" links; see
your friendly manual for details.  (The only problem with such links is that
you can't ping the endpoints directly or netboot across them.)

Since i don't see any obvious problems with your picture, my guess is
that the picture you've drawn does not entirely agree with the actual

We reported the same problem over a month ago and were told new code was
available which corrects this problem.  We subsequently obtained 9.0(1.10)
patch level which so far appears to be holding up, although rings don't
beacon all that often.  In general, this release has made the token ring
considerably more robust in reacting to events on the ring.

The problem (see attached) may be related to the level of
Token-ring microcode you are running. I have a case opened
with cisco dating back to February, case number 15766. They
have not come up with a resolution yet. When I tried to
upgrade from SBEMON 2.0(112) to 3.0(1) I had trouble on
the 4Mb rings that were highly utilized to the point where
the cisco would crash on a bus error. Prior to the crash I
received reset failed messages for the interface. I am
currently running my 16Mb rings on the 3.0 code and my
4Mb rings on the 2.0 code. I just hope the problem doesnt
surface on the 16Mb ring when my users are able to push
it to 90+ %.

Subject: Re: speed capabilities of cisco terminal servers

I don't know whether it is relevant here on the Cisco bulletin board but...

I have done a fair amount of testing of XRemote over SLIP (from NCD X-terminals
 to Cisco MGS). This involved satellite as well as terrestrial (tropo-scatter)
radio. The main outcome of this is that X-remote functions best on LOW DELAY
 rather than HIGH bandwidth. e.g. a link at 9k6 with no delay could outperform
an error-corrected/compressed link at 19k2 with 20msec delay. Don't be misled
by claims of 4 fold compression using v42bis. The data in X-remote is already
heavily compressed by the X-remote satck. It is also error protected by TCP.
The explanation for the heavy dependence on delay is that although it's running
 over TCP with a large window size, X11 has a window size of 1 higher up.
You can run it a 2Mbit over a satellite & it will never use more than 16k.
It is actually then better to run raw X over tcp/ip!

I think the main problem you are going to have is memory hogging, rather than
processor speed. Each user will need approx 100k once they start multi-windows

I await the resulting flaming with bated breath.

Subject: Routers won't talk via fiber interface
Organization: The MITRE Corporation
Date: Mon, 31 Aug 1992 11:16:05 GMT

We are having problems getting two of our routers to speak to each other via
RS-449 interfaces through fiber optic modems.  The first router is an AGS+
running 8.3(3) with (4) MCI cards of varying revision (we're using the board
with v1.7 microcode).  The second router is an IGS running 9.0(1).  Both
routers have DTE appliques.

The modems are Optical Data Systems ODS219 with DCE interfaces and set for a
data rate of 64 kbps.  The modem path has been thoroughly checked out with a
data analyzer, running both local and remote loopbacks from both ends.

When the routers are connected back-to-back with a Black Box modem eliminator,
the link comes up and operates fine.  When the fiber optic modems are
connected, the links stay down, however the control lines from the router do
talk to the modem (e.g. when the router interface is set to loopback, the local
modem automatically switches to local loopback mode).  We've tried various
switch combinations of master and slave clocking on the modems with no success.

Any ideas would be appreciated.  Thanks,

Jerry

Way back in June 92, I had seen this Arp-reply problem occur in 8.3(1)

confirm.  The engineer went back to Cisco and later asked me to try using 
9.0(1) and as you mention it occured again. The Cisco engineer acknowledged it
as a bug and suggested that I try 8.2(7). At that point I was pretty bugged
and told him to try it himself before he suggested it as a fix. He never

We're beginning to start setting up some fast modems.  Apparently
Telebit Trailblazers can go fast enough to use 115Kbps ports, when
using their proprietary encoding and compression.  This isn't a major
concern to me, but even with v.32bis and v.42bis it looks like we'll
be able to keep 57.6Kbps busy.

Our dialups are mostly connected to 96-line terminal servers, which
will shortly be using CSC3 processors.  (I have a feeling we should
have gotten CSC4's...)  We make use of most of the features of
terminal server, including X.remote, compressed SLIP, PPP (shortly),
TN3270, etc.  Obviously we don't expect to see 96 people
simultaneously doing 57.6K file transfers.  (Among other things, it
would come close to saturating the Ethernet.)  But as people start
using some of these newer features, we do expect to see more data
going through these boxes than we've had in the past.  Does anyone
(including Cisco) know what the limits of a single box are for the
normal telnet, SLIP, and X.remote?
