CCIE lab topology - 2600 series

Any reason why R1 and R2 are 2600 series routers in the current topology? I have the opportunity to replace them with 1841s, which I thought would be a good thing since they support 15.x IOS versions.

I know R3 has to be a 2600 series due to the NM-4A/S but would I be ok with the 1841s for R1 and R2?

Thanks!

  • 1841's would be absolutly fine for R1 and R2

    the reason they are 2600's in the current INE topology is to save a bit on cost as the 2600's are quite alot cheaper than the 1841's and supports all the features needed of R1 and R2.

     

    personally i use a 2801 and a 2811 for R1 and R2 so it's all good as long as it has support for 2 serial ports in some way and can run 12.4T

    ohh btw in theory you could also use a 1841 for R3, you would just need to fit it with 2 x WIC-2T or 2 x WIC-2A/S cards to obtain the 4 serial ports needed.

  • The updated topology for the workbooks will use a 2811 for R3 and 1841's
    for R1 and R2. The only interface changes will be to R1 and R2's
    serial interfaces which will go from S0/0 and S0/1 to S0/0/0 and S0/1/0
    respectively.

  • i intend to buy the workbooks as soon as i finish the ccnp track. no changes in lab gear planned?

  • Brian will the new topology take a possible move to IOS 15 into account in regards to IOS 15 capable equipment ?

  • Brian,

    When will the workbooks require R1-R3 be upgraded?  I'm just returning to CCIE R&S studies after an unexpected 18-month absense from home, and was hoping to have to only upgrade R4-R6 in my home lab per this INE article:

    http://www.ine.com/topology.htm

    Thanks for your response and clarification!

    Jeff

  • Any chance you can list what the updated topology will be?  Or will everything remain the same except for the changes below?

     

    The updated topology for the workbooks will use a 2811 for R3 and 1841's

    for R1 and R2. The only interface changes will be to R1 and R2's

    serial interfaces which will go from S0/0 and S0/1 to S0/0/0 and S0/1/0

    respectively.

  • The only thing that you'll see added is MPLS support for all devices.
    It's hard to cover topics like MPLS with only three routers. The
    2600XMs support MPLS but it requires a downgrade of the IOS which isn't
    feasible to do with the rental racks. The other reason to move to the
    1841s is standardization along with space and power.

  • Some of the new TS lab updates will use all routers for MPLS but other
    than that you should be okay. You can downgrade your IOS to support
    MPLS on the 2600XMs.

  • So the new workbook devices will be like this?

     

    R1     1841     2 - WIC-1T
    R2     1841     2 - WIC-1T
    R3     2811     1 - NM-4A/S
    R4     1841     2 - WIC-1T
    R5     1841     2 - WIC-1T
    R6     1841     1 - WIC-1T

    Will the switches stay the same 3550/3560 split like now? 

     

    Sorry to pepper you with the questions, i'm building my lab now and i just want to make sure it'll match up with the future workbooks!

     

  • Yes. The old hardware will also still work but will need to be
    downgraded to support MPLS for a couple of the TS labs.

  • Good-to-go!  So with an upgrade to the hardware for R4-R6 it sounds like I'll be good for the Volume 1-3 workbooks, and can then just use online rack rentals for Volume 4 labs if I do those (or alter IOS on R1-R3 as you mentioned).  Sweet, thanks again for the clarification!

    Jeff

    Some of the new TS lab updates will use all routers for MPLS but other
    than that you should be okay. You can downgrade your IOS to support
    MPLS on the 2600XMs.

  • Deleting post, answered my own question!

  • Yes, 3825s will work.  You’ll just have to change the initial configs to match your interface names and numbers.

    Brian,  Just wanted to double check on this:  Can I use 3825's for R1-R3 and have it be compatible with both the old workbooks and the upcomming ones?  Looking at the feature list i didn't see anything obvious i'd be missing, but just wanted to be sure.  Thanks for your help!

  • When you post via email it strips the sender address, replaces it with @ieoc, and then sends it as unicast to everyone that’s subscribed.  This is why it looks like it was sent just to you but in reality is was sent to the distribution list.  I’m not sure why it puts 127.0.0.1 in some of the messages.  We were never able to get a straight answer on how to fix that from the software developers of the forum.  What you can do is just click on the 127.0.0.1 link, then when it opens in your browser replace 127.0.0.1 with ieoc.com and refresh the page.

  • So have these new labs already been released?  I ended up making this upgrade awhile back to test my own MPLS scenarios but it would be cool if I could follow what's in the workbook too.
