The video demonstrates VRRP configuration on two routers providing an IP gateway. Failover behavior caused by interface object tracking is observed. We also review VRRP packet captured on Wireshark. VRRP serves the same purpose as HSRP with minor differences: one being a standard protocol, hence it would be a protocol of choice for inter-operability with other vendors.

Topic includes
  • Basic VRRP Configuration
  • VRRP priority and preempt
  • VRRP MD5 authentication
  • VRRP Interface Object Tracking
  • VRRP Packet Analysis
Quick Facts:
  • VRRP uses 224.0.0.18 and protocol number 112
  • VRRP has virtual MAC Address 0000.5e00.01xx with xx being group number
  • VRRP default Hello interval is 1 second
  • VRRP default priority is 100
  • VRRP preemption is enabled by default
