Learning objectives

Design two VRRP groups on one LAN to achieve active/active gateway load sharing.
Apply deterministic VRRP election using group priorities and preemption.
Validate VRRP state with show vrrp brief and host-side gateway reachability.
Explain how clients split across multiple virtual gateways achieve both load distribution and failover.

Troubleshooting focus

VRRP group number or virtual IP mismatch between routers prevents a common virtual router from forming.
Missing or reversed priorities lead to the wrong device as Master.
PC default gateway points at a real IP instead of the correct virtual IP.
VRRP preemption omitted causes roles to stay stuck after a reload.
Access ports not placed in the correct VLAN block host-to-gateway reachability.
