Re: IBM 8228 MAU
Please correct me if i am wrong here, but isn't it required to connect RI to RO to form the ring ? I always kept them connected together when using the MAU in a lab environment. To test the ports i can only agree to ElephantChild's method. Greetings Reinhold On Sun, 1 Apr 2001, ElephantChild wrote: On Sat, 31 Mar 2001, John Chang wrote: I have a IBM 8228 MAU.

To test all ports except RI and RO, first connect a machine to port 1 and have it insert into the ring, then connect another to each of ports 2-8 in turn, each time having it insert and checking that the machines see each other. To test RI and RO, you need 2 trunking cables. Connect the 2 MAUs together, then connect the 2nd machine to ports 1-8 of MAU 2 and repeat the insert-and-check test as above. Then, with 1 machine connected to each MAU, test RI by disconnecting first one end, then the other, then both, each time checking that the machines see each other. Reconnect RI and check RO the same way. Warning: If any test fails, it could be the MAU port, the machine, or the cable.

Using a SCO unix box to manage a set of routers
Hi folks, I have a sco unix box which I would like to have 4 vt100 terminals attach to via serial. These 4 vty terminals will be used for students who will be accessing my cisco lab. I'm running into a situation where I can only hook up two vt100 terminals to my SCO unix box because the hardware is Intel and the motherboard has only two serial ports(com1 com2). Where can I get a serial cards that allow me to hook up 4 vt100 terminals to that SCO unix box? I know this is a silly setup. This is a requirement, not an option. Otherwise, I could setup those students to acess via telnet.

IOS DHCP options (2514 and picky CATV server)
Hello, I've hooked up my 2415 running 12.1(2)T to the CATV modem, but I'm having a DHCP problem.

Re: Snapshot Routing Question
According to Caslow, the active time is set on the server using the command "snapshot server time dialer." The configuration line I mentioned was "dialer map snapshot 60 2002," which was taken from the client configuration. The "2002" is the dialer string - the phone number that the client calls. I've actually found the explanation on CCO (wow, who'da thought to look there? ;-). The "60" is a sequence number. In some situations where you would want to configure multiple dialer maps with snapshot routing, the sequence number tells the router in which order to execute the dialer map statements.

Question about frame-relay map statements and frame relay inverse arp
Dear Group, I have been trying to duplicate the problem where if you enter a frame relay map stament in a frame realy interface that is also using frame relay inverse arp that inverse arp will be disabled for specific protocol for that specific DLCI specified in the frame relay map statement. I have reloaded my router, yet the interface still does inverse arp and is able to keep the mapping to the hub and also ,of course, still has the frame relay map statement. My question is this, Has anyone else run into this? Also, I am running 12.09 code and I am wondering if this is something that has been worked around on the 12.09 code. Here is the interface config for the frame relay interface: interface Serial0 ip address 192.168.10.10 255.255.255.0 no ip directed-broadcast encapsulation frame-relay frame-relay map ip 192.168.10.5 211 after the reboot I get this for the "show frame-realy map" : Satellite2R5#show frame-relay map Serial0 (up): ip 192.168.10.1 dlci 211(0xD3,0x3430), dynamic, broadcast,, status defined, active Serial0 (up): ip 192.168.10.5 dlci 211(0xD3,0x3430), static, CISCO, status defined, active According to Caslow books and other publication the spoke router should loose connectivity to the hub router since since it is using frame relay inverse arp to map to the hub router. I have a 2523 as my frame relay switch. Anyway, I still maintain an inverse arp mapping to the hub and do not loose connectivity to it. Anyone have any input on this?

Re: Questions for Next-hop attribute
When an eBGP neighbor forwards routing information to another eBGP neighbor, it changes the next hop to itself. When an iBGP neighbors exchange information they do not, by default, change the next hop. This is where the synchronization rule comes in. An iBGP neighbor will not be able to use a route if it does not have a valid route to the next hop in its IGP. Having synchronization turned on is often unnecessary, so most people turn it off. You still have a problem, though: the receiving iBGP neighbor still might not know how to reach the next hop for any of the routes in its BGP table. To solve this, on your iBGP peers use the next-hop-self command. Since the peers already know how to reach each other, this solves your problem. I hope that helps, and I hope I haven't mischaracterized the issue. I haven't really thought through all of this in a while so I may have some details wrong. If you really want to understand this stuff, pick up a copy of Internet Routing Architectures (2nd Ed.) by Sam Halabi. Another book I really liked is short but sweet. It's BGP4: Interdomain Routing in the Internet (or something close to that.) It's very short but it's an excellent resource. Perhaps you should read that first and then read Halabi. Or you could also get a subscription to Certification Zone and read Howard's papers on BGP, they're quite excellent.

Re: ASN18506 up and running
It was indeed as synchronization problem. My understanding is that in order to bring it from BGP into the routing table, it has to be able to reach the next-hop address from IGP. What's odd is that both WAN links to the upstream ISPs were in iBGP, so I need to read up on synchronization some more. For now, 'no synchronization' fixed the problem. As I posted OT in another post (but perhaps more relevant here): I just installed Zebra on my linux server so I can give people IOS-like access to a BGP router. telnet://r2.artoo.net:2605 with a password of 'bgp' and you can get a look at the world of BGP from AS18506 via UUNET AS701 and Sprint AS1239.

[I'm resending this from my work address because the first attempt didn't appear to succeed.] Forgive me if I missed something but this appears to be the famous iBGP synchronization problem, which I believe can be fixed by turning off synchronization and set 'next-hop-self' on advertisements between your two internal routers. When one router takes external routes and passes them to an internal neighbor, it doesn't alter the next hop attribute. When the other internal neighbor receives the route, the next hop is not the other internal peer, but the external peer it was received from. If the second iBGP peer in this example does not have a valid IGP route to that next hop, the route can't be installed into the routing table.

Re: Cisco training provided by Ascolta
I've taken CLSC and CEMS with them and had excellent instructors both times. In fact, did you see the movie Good Morning Vietnam? If so, do you remember the two expressionless twins that censored the news that Robin Williams could read? One of those guys was my instructor for CEMS!
