2 Dell N3024's (both running 6.1.2.4 software).
The layout here is:
3024-sw1 (Te1/0/2) uplinked to core-sw1 (Happens to be an Arista)
3024-sw2 (Te1/0/2) uplinked to core-sw2 (Happens to be an Arista)
3024-sw1 (Te1/0/1) connected to 3024-sw2 (Te1/0/1) via 10Gb fiber
Basically I want the two N3024's to be MLAG to the core-sw1/2, and I need the two Dells "stacked" but w/o a stacking cable, via MLAG/VPC etc.
As it stands, when this is setup, I have devices that are not reachable on 3024-sw1, unless the link from 3024-sw2 to the core-sw2 is down. MLAG is configured on both cores to each Dell with associated port-channels etc.
I'll gather configs and post them shortly.
In the mean time:
Why do I need to disable spanning-tree on these port-channels to make MLAG work?
Do the Dell's NEED 2 physical links in an MLAG/VPC to work?
Thanks!
