VRRP Vs. HSRP

[navasil]

What are the advantages/reasons to use VRRP (Virtual Router Redundancy Protocol) rather than HSRP (Hot Standby Routing Protocol)? They look pretty much the same feature and performance

[DWAM_2]

I think that HSRP = VRRP from Cisco.

VRRP was normalised inside a RFC (2338) from the work with HSRP.

They have pretty much the same features.

HSRP is more developped about icmp tools (constatation).

About the performance, i don't know.

HSRP is proprietary, VRRP is multi-vendor. I actually prefer VRRP because the primary devices IP address can also be the virtual IP on secondary devices.

The state machine of VRRP is simpler too. I guess Cisco don't feel implementing VRRP on more devices would be good for their sales - it would allow people to be multi-vendor more easily.

Thank you for the answer from both of you (DWAM and Simon).

Also Cisco has now introduced support for VRRP on most platforms in 12.2(13)T:
