We are going to setup a new core network. Is it necessary to enable udld on the gigabit ports? Isn't spanning tree taking over when the gig port is going down.
We tried to simulate this, we enabled on 3 routers spanntree and connected each of them via utp. When i cutted the receiving or sending pair of the utp cable the port detected is as line down, protocol down and spanning tree took over and shutted down the port.
Did we missed something during testing?
