My ISP set up an EPL between my two DCs.... We finally got it up after working with them (they had to swap out equipment) but I have a question about STP.... Should I see STP and CDP between my two switches because I'm not. Each side of the link shows as "root"... I have a VERY basic MST set up with 4 instances . Everything is working with the exception of the MST root issue.. Is it that they are blocking STP across the link? They continue to tell me they aren't blocking anything but CDP and STP seem to be only things not working....
