It will depend on the distribution of your routers towards each of the 5 MDFs.
I need s picture of your topology.
You say there are 5 remote sites, one for a MDF, right?, if so, there should be 5 different networks for each MDF, and in your deployment, all MDFs seem to be in the same network: 10.10.10.X ... it is important to define the mask of each network for each MDF.
How do you connect each remote site to the HQ ?
Topology would help do define the static routes yoe need
