    I was wondering the same. I am not aware of any method to send a single REST call to more than one endpoint. Hence I think the answer should be 1

    I think the same, postman App in chrome can only send command to one URL by That, I suposse that answer should be 1.

    Any other opinion?’

    It’s 1, don’t over think it, Doesn’t mean because there are three you have to write to all three. The one can handle plenty.

    Let’s say you have the ability to write to two, which one would be seen as the source of truth ? Always write to the one don’t try to be fancy.

    sometimes i find the same problem too,
    stuck in vsan initializing,
    and my solution is delete all the configuration in the interface (or make it default) and then re-create the interface configuration again,
    so far this step solve the problem

    Just click the icon of diagram on each device. They will launch a putty instance for that device.
    You don’t need to type ip address on putty.

      Thanks alot once again Lincc…

      On a final Note, access to UCS GUi is also the same way? Just click and Configure via Java enabled GUI?

    After thinking about the SVIs – do we need to configure the SVIs as passive interfaces for OSPF?

    yes indeed…!

    I actually think the consensus says no. I spoke with a colleague that passed the exam and he didn’t recommend doing it.

    • desertlotus

      Interesting….

      Because it would seem as if the SVI would create a neighbor relationship across the VPC in DC1 (???)

      • lithium2k
        July 24, 2019 at 6:53 pm

        Correct but is there any direction to prohibit this?

  16. desertlotus
    July 24, 2019 at 6:56 pm

    That is what I don’t know…. I don’t think it was mentioned or not mentioned for that matter.

    However, OSPF is only established across the DCI for the vPC keepalive and for OTV. Best Practices says to use vPC peer-link for ONLY vPC related traffic…

    One piece of advice I was given is that the test may have you do things that are not best practice. OSPF is only established across the WAN not DCI.

    how to Make sure that DC2-N7K-3 and DC2-N7K-4 uses DC2-N5K-1 & DC2-N5K-2 as equal cost paths?

    my approach would be to play with the metric for those interface I don’t want to be part of ECMP.

  20. CHgeek
    July 24, 2019 at 7:11 pm

    and with …

    fabricpath domain default
    maximum-paths 2

    …use only 2 links for ECMP.

    cheers
