Thanks Csaba! I have a simulation that is more or less working... I have the routes for R1, R3 and R4 but not for R2 I don't know why because I have the same. Anyway, it was enough 
for today     
Enjoy your weekend

well the less the more sometimes....

3 ospf processes for 1 bgp per topology seeems a bit overkill...

you need 1 ospf and 1 bgp per router and it'll be dual stack all   the way 
per tology

have you seeen frederic's validated design? almost the same but with rsvp-te 
to have
"traffic engineering" capabilities offloaded to hardware....
