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.
