you can do transparent bridging between Token Ring and Ethernet. It requires a Translational Bridging..

Hi Ivan, Mac addresses only have local significance. So for your scenario, host X sends a packet with it's own MAC address as the source and the router TR interface as the destination MAC address. The router then rebuilds the packet and sends it out the ethernet interface with the Ethernet interface as the source MAc address and host Y as the destination MAC address.

This is achieved by bit swapping.

RE: Token ring Question. [7:44805]
He said the router is acting as a translation (sic) bridge. So the router (bridge) address does not come into play. The router (bridge) translates the non-canonical TR address to a canonical Ethernet address. The bridge reverses the bits in each byte of the address. We have had many discussions on how to do this. It's as simple as writing your name backwards. For example, let's say one byte was 4A in hex. Put that in binary, one digit at a time. 4A 0100 1010 Now write it backwards: 0101 0010 Put it back in hex: 52 If this seems mysterious or difficult to apply in a generic fashion to any hex representation of a byte, then it's not time yet to go for CCIE.

Re: Token ring Question. [7:44805]
I just noticed that I misplaced the functional/non-functional bit. I hate that! ;-) The functional/non-functional bit is the most significant bit of the 3rd byte (not the least significant bit of the 2nd byte as I said before.) So, the address is: 4000.a089.0002 0100 1010 ... First bit transmitted (most significant of 1st byte) is 0 (specific) Second bit transmitted is 1 (locally-administered) Most significant bit of the third byte is 1 (non-functional) That makes more sense now that I see he was referring to a source address. A source address shouldn't be a functional address.

Re: Token ring Question. [7:44805]
This is correct if the router is acting as a router but when the router is bridging, this is no longer true. To answer your question, Ivan, you would simply perform bitswapping on the TR MAC to find the ethernet equivalent. There were a series of posts on this topic (some by me) that specifically lay out this process in both Hex and binary. Do a quick search for messages from the past couple of weeks for the work 'bitswapping' and you'll find them. HTH, Mike W. C restion wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]...

Re: Token ring Question. [7:44805]
I'm with you 100% on this. I said that bit swapping is as easy as writing your name backwards. Maybe that's a bit of an exaggeration, so to speak, because you do have to do hex to binary and back, but only for a four-digit binary number. So it's as easy as writing your name backwards in Pig Latin. If people don't find it that easy, they should start with CCNA (or a basic math class or a how do computers work class). There's nothing wrong with that. If people can really get CCIE despite finding this difficult, or only because they memorized some charts, I'd be surprised. Don't waste time trying for CCIE. Start with the basics. That would be my advice anyway. Priscilla At 05:19 PM 5/23/02, Michael L. Williams wrote: Priscilla Oppenheimer wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]...

RE: Token Ring Question
If you are atempting to plug two Token-Ring cables into one MAU, just make sure both of those interfaces are on the same network (Which really wouldn't give you much), But just to test this, get two MAU's do not connect them to any part of your network, place one cable in one MAU and the other cable in the second MAU, your beacon errors will go away. The reason you are beaconing, is the first one to initialize is boss, so when you come with another connection, the MAU has already been taken.

RE: token ring question
Thanks for the research, Jim. Jim has shown that when a router attempts to insert into a ring (MAU) with a different ring number than an already-inserted router, it doesn't work. The second router fails to insert into the ring. Here's what happens, assuming you don't use Rodgers Moore's creative Rube Goldberg approach. ;-) The Sniffer trace show this: The two routers inserted fine at first. (Jim must not have made the ring number change yet.) Around frame 792 we see some ring disruption, including some Claim Token frames. The Sniffer becomes the active monitor, which can happen. The ring disruption was caused by Cisco99B leaving the ring, presumably because Jim was starting the reconfiguration. In frame 801, Cisco99B comes back and does its duplicate address tests. Cisco99B gets no responses to these, which is normal. It has a MAC unique address. In frame 806, Cisco99B sends a Ring Initialization frame to the functional group address C002 for the Ring Parameter Server. In frame 808, Cisco927 responds to Cisco99B and includes the information that the Local Ring Number is 000A. (10 in decimal.) Cisco99B goes away then until frame 841 when it makes another feeble attempt to get on the ring. Same thing happens. Cisco927 tells Cisco99B that the local ring number is 000A, so Cisco99B leaves. The result on the Cisco99B screen was: show log Syslog logging: enabled (0 messages dropped, 0 flushes, 0 overruns) Console logging: disabled Monitor logging: level debugging, 0 messages logged Trap logging: level informational, 27 message lines logged Buffer logging: level debugging, 23 messages logged --More-- Log Buffer (4096 bytes): %LINEPROTO-5-UPDOWN: Line protocol on Interface TokenRing0, changed state to down %LINK-5-CHANGED: Interface TokenRing0, changed state to initializing %TR-3-BADRNGNUM: Unit 0, ring number (3745) doesn't match established number (10). %LANMGR-4-BADRNGNUM: Ring number mismatch on TokenRing0, shutting down the interface. %LINK-5-CHANGED: Interface TokenRing0, changed state to administratively down %SYS-5-CONFIG_I: Configured from console by console %LINK-5-CHANGED: Interface TokenRing0, changed state to initializing %TR-3-BADRNGNUM: Unit 0, ring number (3745) doesn't match established number (10). %LANMGR-4-BADRNGNUM: Ring number mismatch on TokenRing0, shutting down the interface. %LINK-5-CHANGED: Interface TokenRing0, changed state to administratively down %SYS-5-CONFIG_I: Configured from console by console ROUTER2# exit So, now we know!

RE: token ring question
I have seen two ip ranges running on a single IBM 8228 mau (you can't get much dumber than that), and I have seen two IP ranges running on a single dumb ethernet hub. The secondary address command allows you to do that with one interface. As far as IPX, I'm not as familiar with that but I don't see why it would be different. What you will see if you do a debug is lots of messages about things arping on the wrong subnet, but things will work. The original post said multiple rings, which is maybe where I'm going wrong with regard to bridging. But if you have two router interfaces with different network addresses and put them into different bridge groups why would that be a problem. daveh -Original Message- From: NP-BASS LEON [mailto:[EMAIL PROTECTED]] Sent: Thursday, November 09, 2000 1:43 PM To: 'Hennen, David'; 'Brian'; [EMAIL PROTECTED] Subject: RE: token ring question HOW I would really like to know this one.

RE: token ring question
IPX doesn't beacon... Beaconing is a Token RIng function that happens at layer 2. IPX happens at layer 3. This is a simple case of OSI confusion (as opposed to OSI envy, which we won't get into...). Token Ring is Layer 2. IP and IPX are layer 3. The Token Ring MAU is part of that Layer 2 ring. At layer 2, with one MAU you have only one ring. BUT - at layer 3, you can run multiple network segments on that same ring. They won't be able to see each other unless you have a router that has an interface configured on each one. For example, take an 8-port 8228 MAU and connect 4 PC's to it. Configure each PC with TCP/IP. Configure 2 of them to use IP addresses 10.10.10.1/24 and 10.10.10.2/24 respectively (and respectfully...). Configure the other 2 PC's to use IP addresses 192.168.16.1/24 and 192.168.16.2/24. MAKE SURE ALL 4 PC's are configured for the same speed (4 or 16). Guess what happens - the 192.168.16.x stations can ping each other, but can't ping the 10.10.10.x's. Likewise, the 10.10.10.x's can ping each other, but not the 192.168.16.x's. NOW - connect a router with 2 TR interfaces to the MAU. Assign one interface to 10.10.10.3/24 and one to 192.168.16.3/24 - again make sure they are both set to the same speed as the PC's. Look at the router's routing table - both networks appear as they are both directly connected. You'll note that the 10.10.10.x's can now ping the 192.168.16.x's and vice versa. OK - that's one issue... BUT there is still the original question which had to do with connecting two routers to the MAU and doing some bridging between them. In the previous scenario, we "virtualized" the network by using addressing at layer 3. This split one layer 2 network into two layer 3 networks. The router was used to connect the "virtual" networks together. In a bridging scenario, we want to connect networks together at layer 2 to "simulate" one larger layer 2 network. Do we have two layer 2 networks? No. Can we use routers to "virtualize" the layer two network, split it in two, then use bridging on the routers to connect it back again? Hmmm... I've held you hand this far - now y'all walk a bit on your own...

The initial question did not mention secondary addresses. They simply stated that they wanted to place TWO seperate routers, with TWO different IP subnets.

What you will see if you do a debug is lots of messages about things arping on the wrong subnet, but things will work.

What happens when you plug two token ring routers into the same MAU and assign different ring numbers to the segment is not fun, you will get an error messages on each router telling you of the two different ring numbers. The first router/bridge active on a segment sets the ring number, all other devices must match this ring number.

Re: token ring question
I'm about to cause problemsa debate or something Something way back in my memory says it is possible to break one MAU into two physical rings. The real problem is that you have to voltage on a port to charge and open a port's bypass relay. If my memory is correct, you make two crossover cables and plug one into Ring in and port 4, the other into Ring out and port 5. The first active connection on one half of the MAU (lets say on port 1) will charge and open port 1 and because Ring out has no bypass relay, the voltage will make it to port 4, charging it, thus causing it's relay to open too, which completes the ring on the first half of the MAU. Now I can easily have this wrong. This actually makes three rings, one of which is un-useable as it involves 1/2 of ports RI, RO, 4 5. Oh!, I think what I'm missing is you have to have an active port on the other half of the MAU too, to complete the charging circuit, otherwise it will flap on and off. Oh hell, I'm pulling this from 1985 memory. It could be totally degraded by now. :) Or was it a Y cable plugged into a port with one pair going to RI pins 34 and the other pair going to RO pins 12 There is a way. I'll sleep on it, but you've got the idea. Someone should try it out. I would, but I don't have a MAU handy.

IBM 8228s have 8 station ports (labled 1 through 8) plus a seperate RI on the left and RO on the right (10 total ports). ---JRE--- Edward Solomon CCNA, CCSI Senior I/T Specialist Networking Solutions IBM Canada Ltd. - Learning Services Tel.: (905) 316-3241 Fax: (905) 316-3101 E-mail: [EMAIL PROTECTED] Internet: http://www.can.ibm.com/services/learning/net_internet.html ___ UPDATED Posting Guidelines: http://www.groupstudy.com/list/guide.html FAQ, list archives, and subscription info: http://www.groupstudy.com Report misconduct and Nondisclosure violations to [EMAIL PROTECTED] --- ___ UPDATED Posting Guidelines: http://www.groupstudy.com/list/guide.html FAQ, list archives, and subscription info: http://www.groupstudy.com Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

RE: Token ring question - Solved!
I'm gonna have to disagree with that statement. At least in part. The MAU that I have, STAR-TEK, ( I can't even find out how old it is, no Url.) 828AT, has 1-8 ports and a Ri and a Ro also.

RE: Token ring question
You might just have a bad MAU. Granted, the 8228 is passive, so this may not be the case. Have you tried to plug each of them in one at a time? If they both fail, get another MAU (Known working). The chance that you have 2 bad 2503s is slim, unless they came from the same place. Hope this helps.

RE: Token ring question - Solved!
Yes, ports can get stuck. Most MAU's have electo-mechanical relays that are activated by a "phantom voltage". That's why you hear clicking noises when a token ring device joins the ring. I've gone into wiring closets where a port is marked "bad", ripped the bad tag off and plugged into a working port. Ray M.

Re: Token ring question
Since you have 2 sets of router and token-ring 9-pin-type1 cable it should be easy to troubleshoot this problem..i would suggest you to try this... 1.. Connect only one router to the MAU. Check if token-ring port inserts into the ring. I ask you to do this because if the other cable is bad it will cause the entire ring to 'beacon' and may not allow any station to insert into the ring. 2.. If this still doesn't work then change the port on the MAU. Usually MAU's don't go bad but i have seen some ports on MAU going bad. 3.. If this doesn't work then change the cable. Make sure cable is correctly inserted..you have to push it hard inside the port...if properly inserted type-1 connector won't come out of MAU port even if pulled unless 'side tabs' are pressed. 4.. If still doesn't work then repeat same steps 1/2/3 with other router. Needless to say (but since you are new to TR) leave RI/RO ports on MAU alone. Don't use them for router..they are used for connecting more MAU's. Above procedure should atleast isolate the problem. Good Luck.
