Re: ISDN Switch - Teleos [7:39556]
What about the SIMLINE 2 ISDN Network Simulator? Has anyone used this one? Check out: http://www.cheapisdn.com I haven't priced ISDN simulators yet though I think the url is trying to tell us something :) This one goes for $1,400 but you can get it on ebay for around $750... Any comments would be appreciated. Scott Chapin, CCNP On Tuesday 26 March 2002 12:43 pm, you wrote: > Does anyone know of a good ISDN simulator ?

Re: Link State Question on Adjacencies- one thought
Tony - First let me say, I am by no means an OSPF guru so I hope I don't add any confusion here. If I am understanding your diagram correctly, all your routers here have point-to-point connections with other routers. With point-to-point links, no DR or BDR is needed. So while adjacencies will be formed between each router that has a point to point connection, a DR and BDR will not be elected in this scenario. Does anyone care to comment?

RE: ip unnumbered
Another thought - You want to keep in mind though, that for troubleshooting purposes, you lose the ability to ping the serial interface because it is ip unnumbered. (IE you would be pinging the lan interface not the serial interface.)

RE: OSPF !!!
Tim - What do you think about just entering the shutdown command on the interface that the current DR is located? This of course will depend upon your network and may not be an appropriate idea. Once the DR is down, the BDR will be promoted and a new election will take place for the new BDR slot. (This of course assumes that you want the current BDR elected to DR.) Once the new election has taken place, you can issue the no shutdown command on the old DR.

Hello all - Unfortunately, I do not have funds to go out and buy an ISDN simulator. I have been looking at POTs simulators as a very cheap alternative. I will still be able to do DDR, PPP, etc. Has anyone had any experience with a Viking DLE-200. It goes for around $135.00.
