Static Routing Configuration with Cisco Equipment

Introduction to Static Routing

• Xavier Marichal introduces the topic of configuring static routing protocols using Cisco equipment, emphasizing the simplicity of the procedure.

• The goal is to enable communication between two computers located in different networks, specifically allowing PC 0 to send traffic to PC 1 and vice versa.

Network Topology Overview

• The topology consists of four subnets:

• 192.168.0.0/24

• 10.10.0.0/30

• 10.200.0.30

• 192.168.10.0/24

Configuring Static Routes on Router A

• To route traffic from the source subnet to the destination subnet, static routes must be configured on each router, starting with Router A.

• The command ip route is used in global configuration mode; it requires specifying:

• Destination network (e.g., 192.168.10)

• Subnet mask (/24)

Defining Next Hop for Static Route

• When prompted by the router, you need to specify the next hop IP address for forwarding packets towards the destination network.

• For Router A, this next hop is set as interface IP of Router B (10.102), which has been pre-configured.

Configuring Routes on Router B

• On Router B, two static routes are necessary due to its intermediate position:

• One route for traffic coming from Router A towards PC 1.

• Another route for traffic returning from PC 1 back to PC 0.

Completing Configuration on Routers

• In Router B's global configuration mode:

• Set a static route for reaching network (192.168.x.x).

• Specify next hop IP addresses accordingly based on desired directionality of traffic flow.

Understanding External Networks and Direct Connections

• Only one static route needs creation in routers directly connected to external networks since they already know how to reach those networks without additional configuration.

Testing Connectivity Between PCs

• After completing configurations, successful packet transmission between both PCs is confirmed through tests.

• Using a traceroute command (tracert), users can observe each hop taken by packets traveling from one computer to another.
