Home Bundles First-Hop Redundancy (HSRP & VRRP) Moving to HSRP Version 2 Advanced Published 2026-07-02
Moving to HSRP Version 2 Bundle lab · $29.99
Migrate a single-subnet LAN from HSRP version 1 assumptions to HSRP version 2, enabling group numbers above 255. Configure HSRPv2 on two routers that share one virtual default gateway IP so hosts retain gateway resilience without reconfiguration.
Learning objectives Configure HSRP version 2 on a shared user VLAN interface Use a version-2-only group number (300) with a single virtual IP that both routers share Verify HSRPv2 operation, including version, group number, virtual MAC format, and multicast address Confirm end-host default gateway reachability through the virtual IP Troubleshooting focus Version mismatch prevents neighbors from forming an HSRP pair Group number out of range for the active version (v1 cannot accept 300) Virtual IP mis-typed or not in the LAN subnet prevents active formation Host default gateway points to a physical IP instead of the virtual IP What's included in the package Work / baseline CML import — lab-work.yaml Topology diagram — topology.svg Print-ready topology diagram (PDF) — topology.pdf Step-by-step learner guide (Markdown — for Obsidian/VS Code) — lab-guide.md Branded PDF lab guide — open in any viewer (Adobe/Preview) — lab-guide.pdf Getting-started README — README.md Verification checklist — verification-checklist.md 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. Download access New here? See how the download → build in CML → grade loop works.
