I bought the CCNP module a few weeks back and am so far very impressed with the quality of the videos and content of the site - well done!
I have some questions around EIGRP which maybe you can help me with.
- Regarding default routes with EIGRP, which is the most commonly used way of injecting a default route into EIGRP? I know you can either redistribute, use the 'default-network' command or advertise a static of 0.0.0.0/0 using the 'network' command, but which do you use in a production environment and why? Is there a best practice associated with this? As far as I can tell, the advertisement of 0.0.0.0/0 seems to be the best as it is not reliant on a Classful address, nor does it produce an AD of 170 when redistributed.
- Is there any particular reason that a loopback interface,by default, has a delay of 50us when created? Is this the same for all IOS versions? It caught me out the other night and was wondering if there are any other caveats with this.
- With EIGRP, is it always best practice to turn off auto-summary? I know it is with RIP but i know that it works quite differently than EIGRP as it always uses classful advertisement when advertised to the same major network?
Thanks and I hope you can help.
