VRRP (Virtual Router Redundancy Protocol, RFC 5798) is the open-standard equivalent of HSRP. Same idea: two or more routers share a virtual IP; one is the Master, others are Backup. The differences from HSRP are minor and mostly historical. This lab configures VRRP alongside HSRP on the same routers to show how similar the two protocols are - and where they differ.
What you will learn
- VRRP architecture and terminology (Master vs Active, Backup vs Standby)
- The VRRP virtual MAC format (0000.5e00.01XX)
- VRRP version 2 (the standard) vs version 3 (newer, supports IPv6)
- How to read

What this lab does NOT cover
- VRRPv3 + IPv6
- GLBP - the next lab, ipc-14
