2 hands-on Gateway Redundancy scenarios you build in your own Cisco Modeling Labs instance and grade against the answer key. Gateway Redundancy configuration and troubleshooting practice for CCNA and CCNP.
Intermediate CCNA lab focused on HSRP preempt behavior. Two routers share a virtual default gateway on a single user VLAN. The baseline already has HSRP group 1 with R1 at higher priority, but HSRP doesn't preempt by default — if R1 reboots, R2 stays active even after R1 returns. The learner enables preempt on R1 so it deterministically reclaims the active role whenever it's up, keeping the intended primary in control. Verification uses show standby on routers and basic host pings to the virtual gateway.
Build a fault-tolerant default gateway on a single LAN using HSRP. Two routers share one virtual IP so a host keeps the same default route even if one router fails. You will configure basic HSRP group 1 with a shared VIP, verify active/standby roles, and confirm the host can ping the virtual gateway.
