Load-Sharing with Two HSRP Groups
Bundle lab
Lab 8 of 13 in First-Hop Redundancy (HSRP & VRRP) · ← Previous · Next →
CCNA exam domain: IP Connectivity
Implement two HSRP groups on a single VLAN so each router is Active for one group and Standby for the other. Two hosts split default gateways across the two virtual IPs for deterministic load-sharing with redundancy.
Learning objectives
- Configure two HSRP groups on the same LAN for load-sharing
- Make R1 Active for group 1 (VIP 10.0.10.254) and R2 Active for group 2 (VIP 10.0.10.253)
- Ensure deterministic elections using priority and preempt
- Verify HSRP state across both routers and host reachability to the correct virtual gateways
- Recognize and troubleshoot mismatched group/VIP or missing preempt issues
Troubleshooting focus
- If one group never forms, check matching group numbers and identical virtual IP on both routers.
- If the wrong router is Active, confirm priority values and that preempt is enabled.
- If a host cannot reach its gateway, ensure the host default route points to the correct HSRP VIP for its group.

How this lab is graded
- Build it your way. Where a lab lets you choose a value — a VLAN name, an interface description — grading checks that you configured it, not which name you picked. Names that another line has to reference, like an ACL applied with
access-class, are stated in the guide and do have to match. - Addresses, modes and protocol keywords are exact. An IP address, a subnet mask,
switchport mode trunk, an encapsulation — these carry the meaning of the lab, so they are graded as written in the guide. - Grading reads your saved configuration. Export the lab from CML after you have configured it, and make sure anything you set is in the
running-config— a change that only exists in a terminal session never reaches the grader. - You can submit as many times as you like. Your best score stands, and each attempt tells you which checks passed so you can work the gaps.
- Scored something you believe is correct? Use Report an issue on this page — that is exactly how the grading fixes in the changelog got found.
