Everything here looks like it's not recognizing that your T1 router has a downlink to a logical switch (once that's done, it knows what transport zone to propagate the DRs to and will advertise the route).
Have you confirmed that on the T1 router, you're seeing the expected logical switch(es) and the uplink to T0 when you go to "Configuration" > "Router ports" in the UI?
If so, do you see any traffic at all when you select the "statistics" icon and is the admin state of the applicable logical switch "up"?
