OSPF routes

[tbk49]

Having trouble redistributing routes between three devices so would appreciate pointing out my mistake, because presumably, it is me rather than the documentation...

Only seeing two routes from R1 populate on another R2, but not in R3.

I have:

R1 connects R2 & R3 via separate IPsec VTIs
R2 connects R3 with another VTI

R1 has two networks to populate in R2 & R3
R2 & R3 have one network each to populate into the adjacent two

It has also been a fiddle just getting OSPF to see the actual neighbors and exchange LSAs even though the firewall rules were present.

What I did was to put the routes on each router into a prefix list, assign that to a route map, then add the route map under 'Route Redistribution' in 'general' tab, per the docs. I had put R2 & R3 in area 0.0.0.1 and for the direction to R1 in 0.0.0.0.

If I do not specify the area under the interface, and I put it under the networks tab, there doesn't seem to be any way to associate an interface with an area so what is the point of using the networks tab? You can't put the area in both places per the help text warning.
