Jensen,

VPLS multihoming assumes you are intentionally building out a loop-free 
VPLS domain.  My situation is when you have a downstream customer who 
unintentionally introduces a loop in their Layer2 domain that causes MAC 
learning table thrashing back inside your VPLS instance.

Thanks for the pointer though.
