CCNA Static Routing: Redundant Branch Triangle

Bundle lab · $29.99

Build a 3-router triangle with two branch LANs and real Alpine clients. Deploy primary static routes via the hub and floating backup statics over a direct branch-to-branch link. Verify reachability, path selection, and failover by simulating a hub outage.

Learning objectives

• Configure bidirectional static routes along a multi-hop primary path
• Deploy floating static routes with a higher administrative distance for backup
• Verify RIB/FIB path selection and host-to-host reachability from real endpoints
• Force a failover and observe floating static installation on both branches
• Troubleshoot next-hop reachability and static route resolution

Troubleshooting focus

• Verify every link's interface status and IP addressing (`show ip interface brief`) and correct any interface that is down or misaddressed.
• Confirm each device's running configuration matches the lab objective, and bring any interface, route, or service that is not in its expected state back to health.
• Trace end-to-end reachability with ping/traceroute and isolate the first hop where forwarding fails.
