Do you have authentication between the Zebra and the Juniper?

It could be. But I find it weird that it succeeds in authenticating with
the Cisco, but not with the Juniper. I'm now trying a new area between
the Zebra and the Juniper, without authentication, to see if it reaches Full.
Address Interface State ID Pri
Dead
192.168.0.1 fe-0/3/0.0 Full 10.0.0.1 130 38
192.168.0.3 fe-0/3/0.0 Exchange 10.0.0.3 0 39
For double amusement, the OSPF on the Juniper has moved to now being
stuck in state: Exchange :) (still in ExStart on the Zebra though).
Thanks greatly for your advice.
