Hi Alex, Thanks for your reply and intrest.
switching ends in the QFX10K, and not extended to the wan routers.
Layer3 for those vlans is configured on the 10K's, those networks are redistributed from connected to BGP towards the wan routers.
P routers (wan routers) sends 0.0.0.0/0 and all IGP table + 0.0.0.0/0 in BGP towards the PEs (10K's)
0.0.0.0 is preferred via isis through the locally connected links to P routers [which I don't understand why it won't go out directly from 10K-2 to the wan, and passes the ICCP link]
hopefully I provided all desired info
Thanks again.
