EIGRP Unequal-Cost Load Balancing with Variance
Build a 3-router EIGRP domain where R1 reaches R3’s loopback over two paths (direct and via R2). You will tune interface delay so the indirect path becomes the successor and the direct path remains a feasible successor, then enable variance to install both unequal-cost paths in R1’s routing table. Two Alpine hosts validate end-to-end reachability while router show commands confirm unequal-cost load sharing.
