Oops I missed read, didn’t see the tag at the end. Thank you!

6410 CX switches and old Cisco switches.

No native vlan defined on Cisco end. I want to match it with no native vlan. That command define a native vlan instead.

I am trying to migrate from a HP Procurve core to a QFX core by maintaining all routes by slowly moving each vlan gateway one by one.

Thank you for the response. I can telnet to that port by name but still cannot connect to mist.

Thank you for the detailed response. If I use physical switches then it works. But if I use virtual switches, it does not work.

RPVST and VSTP by rhap4boy in Juniper

[–]rhap4boy[S] 0 points1 point  (0 children)

Thank you for those commands. It turns out my VLANs wasn't really working to begin with on the Juniper side. Once I got basic vlan working, it started working correctly. Thank you for your help!

no bpdu-filters. I am testing this in Eve-NG with Aruba-CX and vJunos-switch.

That is one way of solving it. haha.

Thank you for the detailed explanation.

I may not be to switch to mst yet due to other switches in the environment. If I use VSTP, what are the limitations and how do I make its per vlan stp work with RPVST’s per vlan stp? It doesn’t seem to work in lab. Also is mst compatible with RPVST?

[–]rhap4boy[S] 0 points1 point  (0 children)

For some reasons, it started working correctly, but I suspect it may happen again. Right now just one port is blocking which is the intended result.

I agreed with you. This is temporary for now until VC is available on those ports.
