Re: ODR, was RE: CCDA: changes in syllabus. [7:72380]
John, I have come across ODR in production a couple of times. Up until recently I had thought that ODR worked quite well for hub and spoke topologies... My most recent involvement with ODR occurred when replacing a 2621 with a 3745, which was the hub of the hub-and-spoke topology. I quickly learned that the 3745 doesn't enable CDP by default. I was also reminded that Cisco doesn't save configuration commands that are considered default... What ended up happening was CDP was not enabled by default and when I enabled it (cdp run) the command wouldn't save because it was considered a default command! Each time the router booted CDP was disabled again! I recommend to everyone that ODR not be used in a Cisco production environment. You never know when an IOS (platform?) bug will render your WAN unusable! - Tom John Neiberger wrote: I've never heard of anyone using ODR.

In addition to that, how many times have you heard that we should disable CDP for security reasons? I'm sure there are some companies that aren't allowed to run CDP for this reason. Then again, that's usually a big company that probably wouldn't want to run ODR in the first place. John Tom Martin 7/21/03 10:05:02 AM John, I have come across ODR in production a couple of times.

ODR, was RE: CCDA: changes in syllabus. [7:72380]
The sixth module is on routing protocols. Top-Down Network Design would meet your needs there with a couple exceptions. The new course covers IS-IS and On Demand Routing (ODR). (Does anyone really use ODR, I wonder??) I've never heard of anyone using ODR. Anyone here know of anyone using ODR in a production environment? Are there any environments where ODR is recommended over other options?
