QUIZES SECTION : https://ipcisco.com/all-quizes/ NETWORK TOOLS : https://ipcisco.com/network-tools/ INTERVIEW QUESTIONS : https://ipcisco.com/technical-interview/ In this confgiuration example, we will see how to configure Cisco GRE (Generic Routing Encapsulation) Tunnel with Packet Tracer. For our GRE Tunnel Configuration example, we will use the below topology and the given IP addresses. Here, we assume that all the IP Configurations have been done and we will focus only GRE Tunel Configuration with Packet Tracer. Let’s start with Router 0. GRE Tunnel Configuration In Router 0, we will create the Tunnel interface and then give this interface an IP Address. After that, we we will define the Tunnel Source, with IP Address or with Interface name. Here, we used Interface name. Lastly, we define the Tunnel Destination IP address. R0(config)# interface Tunnel 1 R0(config-if)# ip address 50.50.50.1 255.255.255.0 R0(config-if)# tunnel source FastEthernet 0/0 R0(config-if)# tunnel destination 20.0.0.1 R0(config-if)# end R0# copy running-config startup-config Now, let’s configure Router 2. We will do the same configuration on Router 2, only IP addresses will change. R2(config)# interface Tunnel 1 R2(config-if)# ip address 50.50.50.2 255.255.255.0 R2(config-if)# tunnel source FastEthernet 0/0 R2(config-if)# tunnel destination 10.0.0.1 R2(config-if)# end R2# copy running-config startup-config GRE Tunnel Static Route After Tunnel configuration, we need to write a Static Route on Router 0 and Router 2. Because, the routers needs to know how to reach to the users connected to the other end router. In other words, because of the fact that the other end LAN is not directly connected to the router, it needs routing information and we provide this with a Static Route. R0(config)# ip route 192.168.2.0 255.255.255.0 50.50.50.2 R0(config)# end R0# copy running-config startup-config R2(config)# ip route 192.168.1.0 255.255.255.0 50.50.50.1 R2(config)# end R2# copy running-config startup-config GRE Tunnel Verification Now, it is time to verification. Let’s verify our GRE Tunnel Configuration. For Tunnel verification, we can use the “show interface tunnel 1” command. And for the IP addresses of Tunnels with other IP interfaces, we can use “show ip interfaces brief” command. gre tunnel cisco packet tracer gre tunnel configuration in cisco packet tracer gre tunnel configuration gre tunnel explained gre tünel konfigürasyonu gre cisco configuration gre cisco explained cisco gre tunnel cisco gre tunnel configuration
