Cool.

If you use 'vrf-target' stanza, by default all route with these extended 
community will be imported and exported.
The auto-export 'stanza' allow to do local route leaking between two (or 
more) vrfs.
This is this special feature that do not work on EX4550 which force do 
to strange things.

I mean using a tagged link between P-PE. This is not recommended and I 
prefer back to back untag link for the core, but in some case it can be 
helpful.

OK cool.

Thks for all theses feedbacks.
