Configuration Roadmap

The configuration roadmap is as follows:

1. Run the dynamic routing protocol on the Switches to implement interconnection.

2. Create tunnel interfaces on Switch A and Switch C and specify the source and destination

addresses of the tunnel. The source address is the IP address of the interface sending packets,

and the destination address is the IP address of the interface receiving packets.

3. Configure the IP address of the tunnel so that the tunnel supports the dynamic routing

protocol.

4. Configure the static route between Switch A and its connected PCs, and between Switch

C and its connected PCs to make the traffic between PC1 and PC2 transmitted through the

GRE tunnel.

5. Configure the egress of the static route as the local tunnel interface.

Data Preparation

To complete the configuration, you need the following data:

l IDs of the VLANs that the interfaces belong to, as shown in Figure 2-6
