Spanning-Tree Port Type Edge & Router

[Ricardo Ferreira]

I am wondering if a switch trunk port that is facing a router that is connected with subinterface can be classified as an edge port in the eyes of Spanning-Tree.

Thanks.

  Yes , that's fine as long as you are not hooking into an installed switchcard in the router.

You should configure the switchport as "spanning-tree portfast trunk"

As Glen says that is assuming you are not connecting to a switch module on the router.
