Inherited this weird DC setup which was meant to be temporary - presence in equinix and cyxtera in CH2 Chicago but with a need to pass a vlan between the two. Was meant to be temporary but has become semi permanent due to other issues in moving out of one of the floors
ASR at each site is passing one vlan through using x-connect over public internet. It's taken is nearly a year to get a proper cross-connect up between the two sites and we are now passing the vlan directly between switches in both sites instead.
My question is, is it possible to keep the x-connect as backup incase the cross-connect goes down (without causing some kind of loop)?
Do bpdus get passed through a x-connect? Would spanning tree save our arse or would it do us over?
