The virtual access interfaces get their ip adrsesses from its
virtual-template interface which again get them from an physical interface
using ip unnumbered,,

It is a L2TP config connected to this interface..

The cpe devices that are connected to each virtual-access interface get /30
nets from an radius server.  What happen if I do redistribute connected is
that in ospf database this addresses shows up as /32

The radius server are at the same time sending an U route to the LNC

core#sh ip route | in 213.162.245.0
     213.162.245.0/24 is variably subnetted, 2 subnets, 2 masks
U       213.162.245.0/30 [1/0] via 213.162.245.1


So if I do a redistribute static, they show up as /30 as they should. Is not
redistribute static the right thing to do here.. Not redistribute connected?

Have Virtual-access interface a IP-address ? 
You can bring interface into OSPF-proccess if this interfase will cover 
network statement and interface must be up/up. 

If doing "redistribute connected" this action don't allow interface send out

LSA  and run OSPF-proccess on it. Consequently show ip ospf int/nei don't 
show any redistruted interfaces and neighbor out there.
