• HQ should advertise both LAN networks via OSPF.
• HQ should be configured to form an adjacency with Branch over the GRE tunnel.
• Disable OSPF updates on appropriate interface(s).

Step 7 Connectivity.

a.  Verify full connectivity from Main_PC1 to the Web_Server in the Secure network.

b.  Verify full connectivity from Teleworker1 to Web_Server in the Secure network.
