4.1 - still not sure what solution "should be"

 

I'm trying to figure out what "the vrf interfaces are different in the question than the solution" means exactly.  Sorry to be a bubble head, but I didn't think there was a way to route between vrf's.  And that was the point.  From R6 perspective it should only be able to ping from VRFA the ip's associated with VRFA.

So are you saying that 192 should be in VPNA and that 172 should be in VPNB ?

OR is this some router trick that I should be able to route from VRF_A on R6 to VRF_B on Sw 1?  The task does say "configure R6 so that you can ping 'between' the abovementioned Loopback subnets."

 

many thanks!!

  • Hi Tammy,

    You are not being a "bubble head".  I do think you are not using the latest version of the MPLS document however.  INE made changes to the lab to try to clarify some of the tasks (this lab was one of them).  So I suggest you download the new MPLS document and give that a try.

    But in a nutshell what the lab is trying to demonstrate is that it is possible to ping across vrf instances using static routes.  Think of it like a "router-on-a-stick" for the two vrf instances.  You can see some of the details of this in the documentation for the lab where it discusses "inter-VRF communications".

    Hope this helps, if not let me know.

  • Hi Terry,

     

    Wow – I didn’t realize the update was just a few days ago.  I
    get that right now.  Thanks for the description.  That explains a whole lot.
