FHRPs: VRRP

VRRP is the standardized FHRP that does exactly what HSRP does, however it works slightly different and can be used in a multi vendor environment.  Here are the differences between HSRP and VRRP:

  • VRRP uses a multicast virtual MAC 0000.5e00.01XX where XX is the hex value of the VRRP group number
  • VRRP uses IOS object tracking to track interface states
  • VRRP defaults with pre-emption, HSRP does not.  Both aare configurable
  • The VRRP Master means the same as HSRP Active
  • VRRP group IP is the interface address of one of the VRRP routers, it is not a virtual IP
