Guys,
I did the cyscoexpert labs today , and I must say O Boy !! what a lab ? Its
really a challenging one, one that resembles the ASET labs that I have
done(someone told me that ASET labs are ex-labs), simple worded, yet carry
so much depth. One must congratulate cyscoexpert on doing a splendid job.
The way we are taught by CCIE's to read the lab(to get an idea), the lab on
first read seems cakewalk.
But the mystery soon starts unfolding. If you are not careful, it can wreak
havoc :) in few parts of the network. The fact that so many *landmines* can
be bundled into a 5-6 router lab (there is no switch, no isdn, no atm, no
voice) is a great job. All the *bells & whistles* that one can think of are
present, ospf auth, recursive tunnel loops, redistribution nightmares,
router-id issues, bgp/ospf synch issues (I took the lab a bit further as
well), ipx & split horizon, ipx sap filtering etc.
I took about 3 hrs, doing the IGP's and I thought the other part was simple,
but I was mistaken . about 5hrs30min later. Then time to reboot, and after
reboot I see the havoc, routes missing/flapping, Router-id issues and what
not. I forgot an important lesson myself, "after starting an ospf/bgp
process, nail the router id's, so if at a later date a higher loopback
address is created and the router is rebooted, it doesnt screw up". Finally
I managed to calm the storm and got things under control about 5 mins, b4
finish time. An independent review by a study partner claimed that *I had
made it :)*
Disclaimer : I havent taken the actual CCIE lab, so I am not sure how this
one fares with the actual one. I havent been asked by cyscoexpert to do this
review. I dont know them. I dont get commission if you take their classes :)
(but I must say, if you take their bootcamps, ask for the guy who prepared
this lab and take his autograph :)
