Captains Log - Destination: CCIE 2012
In the year 2012... on a planet far far away... where the trees were made of UTP cables and had lush seas of binary... there existed a treasure that glistened as bright as looking straight into SFP. This treasure shrouded in mystery, only gave a clue by it's 4 letters... CCIE.
Anyway.. I'm making this as a lab diary type thing.. I wasn't going to bother, but I'm tired of having post it notes cover my monitor and keyboards.

CCIE - COMPLETED!
Comments
The good:
> I kinda get private vlans now... the configuration was tripping me up this whole time.
> Never done q-in-q before.. it's pretty neat and well explained.
> VTP is evil, but it is kinda nifty.
The not so good:
> STP and all it's infamy
> PPPoE still scares me and confuses me
> failback bridging / IRB is weird and scary
OER is MASSIVE...and pretty nifty.. and complicated.. but naturally to do the job OER does, there isn't any simple metric for that.
Going to do a brief summary / review then go out for a thanksgiving dinner!
Finished INE Vol 1, Section 4 - RIP
I went into this one thinking it would be a cake walk and take the least amount of time... talk about a kick to the groin! RIP being as simple as it is.. there's still a huge amount you can do with it and that can go wrong. Also apparently I thought I knew distribute lists fairly well.. but that was proven wrong earlier
The AD distance filtering is cool.. and it's even cooler how you can use route-map's almost like enhanced tracking objects and get clever with null routes.
Lot of really cool stuff with filtering and leak-maps .. I gotta go back over those. Summary addresses tripped me up a bit too.
I did surprisingly well on the key chain stuff considering I've not done it much... the key rotation is nifty.. I may see if I can implement that at work or at least suggest it.
I think I'll take a small break now.. come back to part of it later. Would love to finish it up today as tomorrow I'm going to be gone part of the day, but we'll see.
Kinda started feeling nervous/overwhelmed toward the end this evening... and letting negative thoughts in.. so I figured it was a good stopping point for the evening. If things go well, I can finish up tomorrow morning before I have to leave for the day.. then it's back to the grind on Monday.
> LOOOOTS to review on filtering.. mostly with distribute-lists , leak-maps, route-maps..(well..everything)
> Need to review summarization and floating summarization
> Need to review load sharing and unequal cost load sharing
> Will need to review COST manipulation and how it affects OSPF routing decisions.. BIIIG TIME
Got to go to a family gathering type thing in a bit.. might night get home to study much.. then it's back to work tomorrow and a normal work week..so I probably wont' get to do but an hour a day.
> I feel pretty good about summary addresses.. and it really cleared the confusion I was having.
> I feel a lot better about distribute lists and prefix lists than I did now..
> OSPF has far to many moving parts
> I like pie
> Context sensitive help kicks an unlimited amount of ass
> The more I read about it, the more I like OSPF.. it's a bit overwhelming but right at its' core it's a very "no frills" type of protocol.. far less 'magic' masquerading things
Good luck and lets get our numbers in 2012!!!!
I'm pretty beat from work today.. we've been short handed all week with everyone on vacation. I've got to get up around 7am MST to replace a 5505 with a 5510 at a customer site, then work is having a Christmas party. I didn't want to go but my boss is kinda making me go.
Since I did the CCIP , the BGP stuff is going by a bit easier for the moment.. very good refreshers on clusters, RR's, confederations..etc.
> as-set stuff is really confusing
> I did well on the suppress and unsuppress maps
> BGP is awesome, but it's options are endless.
> I did fairly well on it considering how confusing it was
> The only thing that really trips me up is BGP Conditional Route Injection - marked for review
> BGP Dampening confuses me probably as much as OER does (if not more)
> Local-as is pretty interesting and also confusing at times.. though I 'get' it at a high level
> as-set still confuses me... can't seem to find a cut and dry explanation for it
CCIE #37149
> I definitely need to review the pieces to OSPF and EIGRP with MPLS
> Address families make a lot more sense now.. and I'm a bit clearer on what the address-family ipv4 and address-family vpnv4 actually do.. just another piece to the puzzle
> Feeling pretty good but bad thoughts entering my head again.. trying to discourage me..etc.
> So far to my surprise, multicast doesn't seem as difficult as I made it out to be
> Going through the tasks, I try my hardest to get the answer on my own and research it.. and with a lot of the multicast stuff, I've gotten mostly right or completely right more than any of the other sections.
> I'm hoping to finish multicast this week and keep trucking along to the next section. I've got another xmas party this Saturday and then I'll leave for nearly 2 weeks to visit family.. good time for an extended break.
> High level and theoretical stuff seems fairly simple and straight forward for the most part
> Static mroutes are confusing to me a bit.. Need to really brush up on that
> Will definitely need to review and practice over and over again.. but it's pretty cool what you can do with multicast
> Gotta go over the multicast IP to MAC conversions too
