CCNA lab 23 of 46

First-hop redundancy with HSRP and VRRP

Give two VLANs a default gateway that survives a router failure: HSRP for one VLAN and VRRP for the other, each active on a different router, with interface tracking. Then pull the uplink and read every state change.

Run this lab

It needs Lite: its 6 nodes are set to 6 vCPU and 6,144 MB in total. That fits the free demo too.

The scenario

Highgate Clinic's staff (VLAN 10) and servers (VLAN 20) each have two routers, R1 and R2, both connected to the data centre router R3 (192.0.2.1). The PCs can only have one default gateway, 10.23.x.1, and right now that address doesn't exist anywhere. You'll create it as a virtual gateway: HSRP for VLAN 10 with R1 active, VRRP for VLAN 20 with R2 as master, so both routers carry traffic and either can fail.

PC1 / PC2VLAN 10 / VLAN 2010.23.10.10, 10.23.20.10 (gateway .1)

OSPF already runs between R1, R2 and R3.

What you’ll practise

  • Explain the single default gateway problem and how FHRPs solve it
  • Configure HSRPv2 with priority, preemption and interface tracking
  • Configure VRRP and share the load between two routers
  • Interpret show standby brief and show vrrp brief
  • Test a failover and recognise the virtual MAC addresses

The tasks

  1. Understand the problem
  2. Configure HSRP for VLAN 10
  3. Track the uplink
  4. Configure VRRP for VLAN 20 with R2 as master
  5. Read the details
  6. Fail the uplink and watch the switchover

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 CCNA 200-301 guided labs.

  3. Open 23 - First-hop redundancy with HSRP and VRRP 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.
