R6 sees R4 in broadcast/non-broadcast network mode
150.1.1.4 1 FULL/BDR 00:00:35 183.1.46.4
Ethernet0/0
R4 sees R6 in point-to-point/point-to-multipoint network mode
150.1.1.6 0 FULL/ - 00:00:37 183.1.46.6
Ethernet0/1
That's your problem.
In order to exchange routes, if you go with broadcast, you must have the
neighbor on broadcast or non-broadcast.
While with point-to-point, you must have the neighbor as point-to-point or
point-to-multipoint.
Of course, if you will to change the hello interval if the network mode are
different from the ones mentioned above.
