VRRPv3 for IPv4 and IPv6

Give the Glasgow branch LAN a standards-based redundant gateway with VRRP version 3 for both IPv4 and IPv6, uplink tracking and tuned timers, and compare VRRP with HSRP and GLBP.

Run this lab

It needs Lite: its 5 nodes are set to 5 vCPU and 2,560 MB in total. That fits the free demo too.

The scenario

Fernhill Freight's Glasgow branch has two routers on one LAN, and the PCs point at 10.30.10.1 as their gateway. Glasgow's routers came from a partner who insists on open standards, so instead of HSRP you'll use VRRP version 3, which handles IPv4 and IPv6 in one group:

  • Group 10, IPv4 virtual address 10.30.10.1 and IPv6 link-local virtual address FE80::1.
  • R1 is master (priority 120); R2 is backup (default 100).
  • R1 tracks its WAN interface and drops by 30 if it fails; R1 waits 20 seconds after recovering before taking the role back.
  • Advertisements every 500 ms for faster failover.

OSPF already connects R1, R2 and R3.

Topology: R1, R2, PC1 and PC2 share the Glasgow LAN; R1 and R2 each have a WAN link to R3.

What you’ll practise

  • Compare VRRP with HSRP and GLBP: standard, roles, virtual MAC, pre-emption and timers
  • Enable VRRPv3 and configure IPv4 and IPv6 address families on one group
  • Use priority, pre-emption delay and object tracking to choose and move the master
  • Verify VRRP state, virtual MAC addresses and host reachability

The tasks

  1. Address the PCs
  2. Compare the protocols
  3. Turn on VRRPv3
  4. Build group 10 for IPv4 and IPv6
  5. Track the WAN and delay pre-emption
  6. Test it

The Lab Tasks pane has the scenario, these tasks, the checks to run, hints and the full solution.

How to open this lab

  1. Sign in to your workspace at lab.cloudlabbox.com.

  2. In File Manager, open Shared, then the folder CCNP ENCOR 350-401 guided labs.

  3. Open 20 - VRRPv3 for IPv4 and IPv6 and start its nodes, then open Lab Tasks for the scenario and the steps.

The lab is read-only. You can start the nodes and configure the devices, but changes to the topology can’t be saved. To change it, rebuild it in your own folder.
