I wouldn't call it load-balancing so much as it's load-sharing. On routers
where you have multiple interfaces for VLANs configured, you can make one
router the primary for certain interfaces/VLANs and the second router the
primary for the rest.
Here's a sample config showing what I mean.

Isn't HSRP used more for fault tolerance than it is for load balancing?
Actually, I've never even heard of the two (HSRP and Load balancing) going
together. At least that's what I got from reading up on it. Please let me
know where I am confused.

If the automobile had followed the same development as the computer, a
Rolls-Royce would today cost $100, get a million miles per gallon, and
explode once a year killing everyone inside.
