I am a little bit confused when we talked about inter-area TE and L1/L2 ISIS routers.
I have 8 L1/L2 routers in a partial mesh, these routers belong to different ISIS areas.
As I understand ISIS implements a topology table for the L2 routes and thus a TE Tunnel is always possible between L1/L2 routers even if they belong to different area ids.
Inter-area TE only solves the issue for tunnels between L1 only routers belongging to different areas.
Am I correct? Can I go forward and configure a TE tunnel between L1/L2 routers in different areas?
