This Friday concludes the 3rd week of INE’s Live CCIE RSv5 Advanced Technologies ClassClass will tentatively continue on Monday June 30th 2014 at 08:00 PDT (15:00 UTC), with advanced BGP  designs and applications.  Tentative class dates for next week beyond this are Tuesday July 1st and Wednesday July 2nd with the same start time of 08:00 PDT.

I list these dates as tentative because they are all dependent on Baby McGahan 3.0, whom is officially due on July 15th.  Essentially as it stands I am on permanent 24/7 on-call rotation for baby to arrive at any second.  E.g. don’t be surprised if I pick up my phone during class, and then immediately walk off camera with no explanation.  Baby 3.0’s arrival is eminent ;)

For those of you that have been attending live, I would like to thank you for your input during class, especially during Q&A sessions; the more you put into class the more you get out. My video team is hard at work on posting these new videos on the RSv5 ATC streaming playlist, and also the downloadable RSv5 ATC videos.  In the meantime, the previous RSv4 ATC playlist can be found here, which covers many of the core topics of RSv5 along with some of the Transition Technologies that I added to the end of the playlist.

Going forward, the following is a list of key *new* features to RSv5 that we have not yet covered (we will be covering them).  However, if you want to do some homework this weekend on any of these new topics, you can find a list of recommended books, documentation, cisco live presentations, etc. below that cover these.  The overall RSv5 ATC outline can be found here as our CCIE RSv5 Expanded Blueprint.

Happy labbing this weekend, I hope to see you all back for Monday’s class!

In a recent post I talked about Using Config Replace For Managing Router & Switch Initial Configs.  This is a great feature that can be useful to quickly switch between initial configs and a default config while labbing on your routers without having to write erase and reload – which can be very time consuming.  However, I previously assumed that this required a staged “blank” config in the router’s flash, because regular IOS and IOS-XE don’t have a built in text editor such as vi/nano/pico that would let you create a blank file on the router’s flash.

Thanks to my buddy xous in #cisco on irc.freenode.net, I found that you can use TCL to write a file to flash through the IOS CLI, the same as if it was a native text editor.  The end result is that you can use the following code to write a blank config file at any time to rollback to.

tclsh
puts [ open "flash:blank.cfg" w+] {
version 15.4
!
end
}
tclquit

An example implementation of this is as follows:

R1#show ip int brief | exclude unassign
Interface              IP-Address      OK? Method Status                Protocol
GigabitEthernet1.13    155.1.13.1      YES TFTP   up                    up
GigabitEthernet1.100   169.254.100.1   YES TFTP   up                    up
GigabitEthernet1.146   155.1.146.1     YES TFTP   up                    up
Loopback0              150.1.1.1       YES TFTP   up                    up
Tunnel0                155.1.0.1       YES TFTP   up                    up      

R1#tclsh
R1(tcl)#puts [ open "flash:blank.cfg" w+] {
+>(tcl)#version 1.1
+>(tcl)#!
+>(tcl)#end
+>(tcl)#}
R1(tcl)#tclquit
R1#config replace flash:blank.cfg
This will apply all necessary additions and deletions
to replace the current running configuration with the
contents of the specified configuration file, which is
assumed to be a complete configuration, not a partial
configuration. Enter Y if you are sure you want to proceed. ? [no]: yes
Overwriting with a file sized 50% or less than running config's. Proceed? [no]: yes
% Be sure to ask the CA administrator to revoke your certificates.

*snip*

Router#
Router#show ip int brief | ex unassign
Interface              IP-Address      OK? Method Status                Protocol

Router#

The end result is that you can at any time default the router’s config without having to erase and reload. Note that there are certain caveats such as deleted subinterfaces on Ethernet or Serial links which will still exist as “deleted” in the running config, but in most cases for our applications this will not be an issue.

Also as a shameless plug for IRC feel free to join the discussion in the channel #cisco on irc.freenode.net and chat with us. You can find me there with nick bmcgahan.

Happy labbing!

Earlier this year in April, we reported to you about a major change in policy to retakes of the CCIE Written and Lab exam. Just today Cisco updated that policy with a major blow for anyone who has been preparing under the old pretenses. Namely that: “These policy changes will be applied retroactively from the date of a candidate’s first lab attempt.” The seemingly innocuous announcement can be found on their CCIE Lab Policy page, just above the table indicating how long you must wait between attempts. This means that if you already have, for instance, two attempts (and unfortunate fails) going into August 2 (when the new policy goes into effect), you would have to wait 90 days from the time of your last attempt to retry the exam. This still gives folks a chance to get another attempt (or 2, possibly) in before this Aug 2 deadline, regardless of the number of previous failed (or missed, if you simply didn’t show) attempts. But of course the real goal of Cisco here is to try to get you to study harder before even attempting your first CCIE Lab – which isn’t a bad idea for everyone.

So as always – Happy Labbing and STUDY HARD!

Whe you are plugging along with your studies or enjoying a cookout today – I thought I’d post a short video to make you smile today. If you couldn’t make it out to INE’s Rewired party at Cisco Live this past week in San Francisco, or if you just had to leave early and catch the end of the CCIE Party, you missed something special. This is our very own Brian McGahan shredding it up with the band. I think he was sad that he couldn’t stay to see Lenny Kravitz play, and felt the need to participate in his own way. He may have imbibed before this took place, so you’ll forgive him ahead of time if there is a time or two where he’s off tempo.

Anyway, enjoy! And Happy Memorial Day!
