One of the great new features that was introduced in IOS 12.3 is BGP conditional route injection. With conditional route injection we can insert more specific routes into a BGP table based on the existance of another route. Most of the routes in the current internet BGP table consists of aggregate routes. This is used to minimize the size and number of routes in global BGP routing table. The aggregation of routes can sometimes obscure more specific and accurate routing information. Wouldn’t it be cool if we could control and “un-aggregate” those routes on demand? Well that’s kinda what BGP conditional route injection does. It allows us to originate a more specific prefix into the BGP routing table based on an existing aggregated route.

I got 70%. Pretty disappointed about this one, as I missed some easy masks. Some I lost because of the grading again looks for very specific answers (although I think this grading script was better than the last one).

It looks like even if you don’t have access, or you think you might require access to a DocCD resource that is missing, the proctor is able to give you access to those missing/broken links. This was from the proctor in the Sydney lab as well, so that is a bit of a relief. I am still going to make sure I know how to find the information on all the versions of the DocCD, but it is still nice to know.

Let’s say you have a scenario that says we want to configure R2 such that all inbound traffic marked with an IP precedence of 5 and 3 should be limitied to a maximum of 1Mbps. Anything above this rate should be discarded.

Sounds simple enough. What are the different IOS tools that you can accomplish this?

I just finished my CCIE Assesor Lab A. I got 72%. I have mixed feelings about this one. The script looks for very specific answers but it gave you a fantastic insight on what Cisco is looking for in terms on configuration and how they mark your exam….

Try it. lol

I ran into this strange problem while doing Mock Lab 6, and I thought it warranted an article because it highlights why the order of operations that IOS performs certain tasks is important.
