Node 1
Router 1
To maintain DCN resilience, static routes are used and a GRE tunnel is created between Router 1 and
Router 2 over the DCC/OSC/GCC optical link. In this example, all ONS 15454s are part of the same
subnet. Therefore, the Router 1 and Router 2 static route tables have more entries because alternate paths
must be configured for every host.
