Thank you all for the help here.  I have one last  question on this 
matter.  Is there more config that needs to be done on the juniper side 
to load balance across these links?  I see in the cisco I can configure 
it to balance based on MAC sorce/destination.  I have read that the 
juniper does this based on IP destination.  Does it do so by default?  
The documentation I have seen is very gray in this area.  Thanks.. //db
