Home Bundles First-Hop Redundancy (HSRP & VRRP) VRRP — The Open-Standard Alternative Advanced Published 2026-07-02
VRRP — The Open-Standard Alternative Bundle lab · $29.99
Replace HSRP with open-standard VRRP to provide a shared virtual gateway on a single access VLAN. Configure VRRP group 1 with a common virtual IP and deterministic master/backup roles via priority and preempt. Validate using show vrrp commands and end-host pings.
Learning objectives Configure VRRP group 1 on two routers that share one user VLAN Set deterministic master/backup roles using VRRP priority and preempt Verify VRRP state and VIP ownership with show vrrp and show vrrp brief Confirm end-host default gateway reachability through the VRRP VIP Troubleshooting focus Mismatch in VRRP group number or virtual IP prevents neighbor formation Forgetting preempt on the intended master can leave the wrong router as master Host default gateway must be the VRRP VIP, not a router’s physical address Access ports must be in the correct VLAN for all devices on the shared segment 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.
