Route 1.0.0.0/8 is the optimal.
Method II: Configure different local preferences on Switch B and C for route 1.0.0.0/8,
making Switch D give priority to the route from Switch C.
# Define an ACL numbered 2000 on Switch C to permit route 1.0.0.0/8.

# Configure a routing policy named localpref on Switch C to set the local preference of route
1.0.0.0/8 to 200 (the default is 100).
