I am attempting to run this NSO Sandbox Lab. It starts ok and I follow the instructions on this DevNet learning lab. However the distribution switches in the lab - namely dist-sw01 and dist-sw02 - simply fail. I cannot access them from the managemen...

I'm trying to confirm SR to replace 6PE in a lab that I'm running. I've attached a couple of pictures to show how I understand the setup to work (and to show how bad my handwritting is and how much I love to color code ) Firstly this is how I unders...

Actually sorry. I might have jumped the gun. So that lab above, with a weight of 1, was a lab whereby I had converted the IGP from IS-IS to OSPF. I did this incrementally and found various problems getting tunnels to come up, resulting in me having t...

Hi Peter, Thanks for the response. I think my problem might be related to https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvs74549/?rfs=iqvred. I'm running IOS-XE version Version 16.6.5, which is covered under this bug. I'll test this in a lab and ...

Sorry perhaps my discussion is misnamed, my concern is not regarding the actual sham-link itself. Its about the down bit not being set (which is a check I performed before configuring the sham-link). If I use route-maps to filter the loopbacks enteri...
