hsrp same priority

I am using hsrp at my core switches. I accidentally configured priority 150 for both core switches. I thought that it would load balance. But I still see one is active and the other one is standby. Can the experts explain the hsrp process in selecting the active and standby with the same priority? Thanks

If priority is the same, than highest ip address will win the election.
There is no load balance in HSRP as it has been developed at 1994.
For load balance you need to use - GLBP.

Is it highest or lowest IP address? The reason I ask is because my core 2 (192.168.1.2) is currently the active and my core1 (192.168.1.3) is the standby. Thanks

PS. I forgot to mention but preempt is enabled on both core switches
AlexBlinovCommented:
Highest.
But since the "Preemption" is off by default - the reelection won't happened unless you turn it on the the interface with the highest ip address.

like:
Router1(conf-inter)#interface fa0/1
Router1(conf-inter)#standby 1 preempt

You can have load balancing with HSRP. Let's say you have VLANs 10, 20, 30, 40, 50 and 60.
The way you do it is to make the first router active for  VLANs 10, 20,30 and standby router for VLANs 40, 50, 60, and you make the second router active router for VLANs 40, 50, 60 and standby router for VLANs 10, 20, 30. Also you should accordingly adjust root bridge for those VLANs to match those criteria. Sure you need to set preemption on both routers, and also it is highly recommended to set some delay for preempt period, so router don't become active right away after it loads IOS. Reason for this is maybe router is faulty, and constantly reloading itself, to give router time to fill routing table etc...

If preemption is not set on routers, the first router that boot up will become active router, and  the other router will become standby router. So in that case, while currently active router is not rebooted, or failing there will be no reelection process..
