This configuration demonstrates how to set up OSPF and EIGRP routing protocols on Cisco routers. It includes configuring interfaces, routing protocol processes, network statements, passive interfaces, and redistribution of routing information.

Please note that this is a basic configuration example and may need to be modified based on your specific network requirements.

Important: Remember to replace any placeholder values (e.g., IP addresses, passwords) with your actual network information.
