That's not it :-). I mean, yes, BPDU Filter will "fix" the problem, i.e. make it disappear, but that's not the cause.
Now - why you haven't encountered this before, I do not know. I even can't recall if this is actually part of the lab, but it's an interesting problem nevertheless. Something that's entirely possible to face in the lab. Again, hint - it's not AToM error. It's something else. Read the error message. -- Marko Milivojevic - CCIE #18427 (SP R&S) Senior CCIE Instructor / Managing Partner - IPexpert On Tue, Sep 3, 2013 at 11:35 AM, Saleh Batouq <[email protected]> wrote: > Hi Marko, > > Port fa0/0.211 of on R2 is encapsulating DOT1Q for VLAN 211.
