IPexpert Volume 2 Section 11 Review

I just completed this lab in about 4 or 5 hours. I spent the first hour (before my session even started) reading the lab, redrawing the L3 topology and making a task checklist. This actually took me about a half hour. I got an estimated score of 89, missing 4 tasks for 11 points. Two were easy, but the other two...well, just proof that I need to review the DocCD :-)

Here are the misses:

-3 Task 5.4 EIGRP
Routes should be dropped from inactive neighbors in half the default time. I used hold time command, but the PG had "timers nsf route-hold 120" as the answer. I need to review NSF.

-3 Task 6.1 RIP
I forgot to enable v2-broadcast on one interface. BONEHEAD!

-1 Task 8.7 BGP
Completely misunderstood the aggregation task. BONEHEAD #2!

-4 Task 10.2 DNS
We needed to create a domain list with "ip domain list". I just used the domain-name command. I am not familiar at all with how DNS resolution works on Cisco routers so I need to review this.

Over the last few months I have increased my speed and efficiency dramatically. Time does not seem to be an issue anymore. When I started studying in the spring, I was taking so long on full scale mock labs, I stopped doing them. Many commands I know by heart, but occasionally I misunderstand a question or just have the wrong command like the EIGRP section above.

Now that I have more time, I use it to prep before I start. This includes reviewing and drawing the topology. I want the processes I use on the practice lab to be just like the ones on the real lab. That way nothing is new and I can get in my comfort zone. I definitely "feel" ready for the real thing, but that doesn't mean I am.

I can still think of some topics that would give me a hard time, unfortunately I haven't seen to many of these lately...but I know they are there...waiting to get me ;-)

  1. Looks like my DNS question was right. The only difference between "domain-name" and "domain-list" is that the latter allows more than on entry.

    From the DocCD:

    "You can specify a default domain name that the Cisco IOS software will use to complete domain name requests. You can specify either a single domain name or a list of domain names. Any host name that does not contain a complete domain name will have the default domain name you specify appended to it before the name is looked up.

    Note If there is no domain list, the domain name that you specified with the ip domain name global configuration command is used. If there is a domain list, the default domain name is not used. The ip domain list command is similar to the ip domain name command, except that with the ip domain list command you can define a list of domains, each to be tried in turn until the system finds a match."
