Hi Chin-

I think your slides blend two separate issues: EROS; and Resolving loop path ambiguity of bidirectional STPs.
The path ambiguity is a artifact of loops in the inter-domain topology, not EROs.
I have added two slides to your deck (see attached) that explain my point.

We can discuss at the call

Hi all,

Sorry for not getting this out sooner.

There has been some discussion in a smaller group on how to resolve the ambiguity of EROs that use bi-directional STPs. I've tried to capture the proposed solutions from the discussion and present them in the attached slide deck. I apologize to the folks in the discussion if I misrepresented your proposals, please feel free to make corrections.

Thanks.
