You are tasked with optimizing and troubleshooting an EIGRP network. The network has multiple routers, and you need to ensure efficient routing and resolve any issues affecting convergence time. Provide the necessary configurations and steps to achieve this.

Answer: This would require configuring EIGRP stub routing, fine-tuning EIGRP metrics, and addressing any potential issues with hello and hold timers.

Set up an MPLS L3 VPN between two routers using BGP as the PE-CE routing protocol. Ensure proper route distinguisher and target configurations, and verify the connectivity between customer sites.

Answer: This would involve configuring MPLS, BGP, and VRFs, as well as implementing the necessary route distinguishers and VPN targets for customer separation.

Design and configure a network with both HSRP and GLBP for redundancy. Ensure proper load balancing and failover between routers. Include troubleshooting steps for any potential issues.
