Virtual Router Redundancy Protocol
HSRP is a Cisco proprietary protocol, alone accessible on Cisco devices. Nonetheless, it is such a useful
protocol that added vendors accept capital article agnate in the accessible standards domain.
The Basic Router Redundancy Agreement (VRRP) is an Internet standard, authentic in
RFC 2338. Specifically, VRRP specifies the agreement amenable for selecting one of a accumulation of
VRRP routers on a LAN to be the Master. Any of the basic router IP addresses on the LAN
may be acclimated as the absence router by hosts application a statically configured absence gateway.
The Master VRRP router assiduously packets beatific to IP addresses associated with the
VRRP group. As with HSRP, the acclamation action has activating failover should the Master
become unavailable.
There seems to be no accessible account to alteration over to VRRP if you are already running
HSRP in a satisfactory configuration. But if you intend to mix with some non-Cisco routers or
have a bee in your beanie about proprietary protocols, again a change may be required.
