VRRP VS HSRP

What are the differences between VRRP and HSRP?

Besides VRRP not being proprietary, there are a few minor differences between the protocols as well:

With HSRP, each interface must have an IP address that is separate from the HSRP group address. VRRP lets you share the Master's interface IP address.
On Cisco devices, VRRP is configured to preempt by default, whereas HSRP is not configured to preempt by default.
On Cisco devices, HSRP sends hellos every 3 seconds and has a dead timer of 10 seconds. VRRP sends advertisements every 1 second and has a dead timer of roughly three times the advertisement interval.
VRRP can be configured to learn the timer configuration from the Master.




HSRP
1) Cisco propriteray

2) 1 Active & 1 standby router & 1 or more listening routers

3) use virtual ip add as gateway

4) hello 3 sec & holddown timer 10 sec

5) we can enable preempt manually (standby 1 preempt)

6) multicast at:224.0.0.2 (ver1), multicast at:224.0.0.102 (ver2). Both versions use udp port 1985

VRRP
1) open standard (ietf)

2) 1 master & 1 or more backup routers

3) real ip address can be used (highest ip address of interface)

4) 1 sec & hold-down timer 3 sec

5) By default preempt is enabled

6) multicast at:224.0.0.18 – IP 112
