Is this possible:


         +------R1--------+
         ^   Area 0       v
         ^                v
        N1                N5
       /  \             /    \
     /     \          /       \
   N2  area N3------N6  area   N7
     \  2   /         \   3   /
      \    /            \    /
        N4                N8

N1-N8 are OXC nodes.
R1 is a router providing control plane connectivity.

All Na-Nb links are TDM links and provide control plane connectivity except
N3-N6 where control plane connectivity is provided out-of-band. All Na-Nb links
have TE attributes that need to be advertised.

Links N1-R1-N5 are not TE links.

If the service provider requires that N1-N4 needs to be part of area 2 and N5-N8
be part of area 3:
1. Can N3-N6 be advertised at all?
2. Can you couple two area (2 and 3 in this example) from a TE topology point of
view but not for the regular topology?
3. Based on answers for 2 and 3, would N3 and N6 need to establish ospf
adjacency?

Please post your replies to the list.

Thanks
