Stuff to go over again

This is what I will be doing next, just to recap then ts off to the land of the big bad assessor lab!

MST - not hard, but I dont get much exposure to this so I will do it again

DAI/DHCP Snooping - not something I do much either

BGP - Conditional advertisement, aggreration with leaking specific routes, communities and regexp (is there anything else left in BGP? :P)

Multicast - not difficult, but not exposed that much to it.

IPv6

I lied.  I am working on IPv6 now.  I’ll do IP Services later.  I am pretty happy with IPv6.  Unfortunately the NM-16-ESWs in my 3640s on Dynamips have a fart when you try and configure an L3 Etherchannel between them.  Now I dont know if this is a Dynamips specific drama, if its the IOS I’m using, or if its the NM-16ESW itself.

Creating a port-channel interface Port-channel1

OK, L2 channel seems ok

SW-1(config-if-range)#
*Mar  1 01:22:15.135: %EC-5-BUNDLE: Interface Fa0/14 joined port-channel Po1
*Mar  1 01:22:15.171: %EC-5-BUNDLE: Interface Fa0/15 joined port-channel Po1
SW-1(config-if-range)#no switchport

Lets try making the channel group then making it L3 after

SW-1(config-if-range)#

Up yours Cisco!!!

Played around with it for a bit… Traceback city no matter what I did.  Im not that fussed though, Im pretty happy with RIPng anyway.  I already know how to make L3 Etherchannels so its all good.  I might come back later and just do some inter-router RIPng stuff rather than trying to do it over L3 Etherchannels.  It’s no different really.

Narbik’s OSPFv3 labs are just router only… Let’s try those.

Speed hump

Why is when I am halfway through an 8-hour lab I always want to type:

redistribute yourself!

metric $@#@!

route-map &%^@!

Finished Soup-to-Nuts!

I finished Narbik’s book today. Pretty happy with that I might add. Certainly picked up a few gotchyas on the way through there. I just hope I remember them all for the upcoming months. Tomorrow I will go over the things I had trouble with on the InternetworkExpert CoD. Then I will repeat those sections of soup-to-nuts again and see if I do better.

One thing that has an incredibly high suck factor is the fact IPv6 does NOT WORK over frame-relay on my lab setup.  I tried various methods of configuring (point-to-point, multipoint, frame maps) and nothing.  I’m not that fussed though…  I went through the answers thinking “I would type this line here” and there they were were I wanted them.  A few things were different but thats all good.  I havent done enough testing to see if it is a problem with the IOS I am using or if it is something else.  My guess is IOS rather than being a dynamips/GNS3 problem because the frame mappings work fine with IPv4, as well as running IP across the links.  So Im saying IPv6 IOS bug…

Im going to be generous once again and include the startup-configs I rewrote to work on my dynamips setup.  I improved the configs as I went through the lab so some of them might not be a straight copy and paste, also some labs I did not edit as they had the same initial config as a previous lab.  You will find these here and there.  So if these things save you about 15-30 mins on the start of 90% of the labs I am sure you wont be complaining to me too much :)

Now to open a bottle of some fine Barossa Valley Shiraz.  mmmm

CCIE is Easy!

Right now I am working on the IP Services section of the Soup-to-Nuts book.

When you think about it… Any day on the job says, “go and configure xxx” “set the network up to yyy” or you might think, “something would work better if I did zzz” Normally you go away for a couple of hours and come back and its done and everyone is happy… You normally get it right too.

You might even get presented something you havent seen before. I just finished the lab on DRP in the IP Services section of Narbik’s book. I have never seen DRP before. All you need to do is press the ? key a few times and the answer is in front of you. Check the answer guide and all the work I did was right.

I think we can carry this on to how a medical professional would work.. A doctor could patch someones bleeding up. A doctor could reset a broken arm. A (specialist) doctor can perform open heart surgery.  Just like a specialist network professional can configure OSPF, tweak BGP peerings and halt a nasty DoS attack.

Now… Can a doctor reset a broken arm, do some nasal surgery, remove a cancerous growth and combat a cardiac arrest all at once and sort it all out within eight hours and have the patient mobile, living and otherwise fully  at the end of the operation?

CCIE is easy!  All you need is the ? key.  Who am I kidding? :P

Welcome!

This is my first post of my under construction CCIE blog. Speaking to Arden convinced me to start so here I go.

I am studying for my CCIE (Routing and Switching) at the moment. The materials I am using are:

InternetworkExpert Workbooks and Class on Demand. The CoDs are FANTASTIC and are a requirement if you wish to pursue your CCIE.
