IPexpert Volume 2 Section 13 Review - PART I

Well I am 2/3 of the way done here with a couple hours to go, but I am going to finish this next week. I have a terrible cold or something...I don't know, maybe it's all the Hot Pockets I ate this week. Whatever it is...I AM DEFEATED for the day.

I semi-graded this thing and I must say this is the TRICKIEST/HARDEST lab of them all. There are a total of 58 tasks, each worth 1 or 2 points and a few worth 3. This is the longest lab I have ever done to date. I am not entirely sure I would have finished in 8 hours...if I did, I wouldn't have been able to grade or verify much.

I think I missed about 7 or 8 tasks for about 15 or so points so far. Definitely a failed effort, but there were some good lessons learned. Here is a summary of what I had to configure:

-Fallback bridging. I actually got this right

-Only allow NetBIOS over TCP/IP in vlan 999. Used a VACL but I didn't what ports to match for netbios. I used range 135 - 139 but I don't know if this is right.

-Make sure CAT1 never becomes root for VLAN 999. The PG disabled STP for this VLAN, I used bpdufilter on the ports in VLAN 999. The PG was probably more correct.

-If R4 detects PVC states other than invalid, active or inactive - notify the trap receiver. What traps are these??

-Then there was a task that had me configure a secondary address on an interface that already belonged to Then you were supposed to filter out RIP routes on this subnet - HUH? I have no idea if this was a typo or what but the PG was really bad at explaining this one. I am not going into more detail - see it for yourself :-)

-OSPF task that had two different authentication keys on the same interface. This was a little tricky but I got it to work. I remember seeing this on GS so that helped a lot. You had to use neighbor statements on the spokes instead of the hub.

Anyways. this lab is truly a mind-number. Just the kind of trickery to expect on the lab, I assume. If you think you are hot stuff - try this one ;-)
