two or more routers into a standby group that shares an IP address and MAC address and
provides a default gateway. When the IP and MAC addresses are independent from the routers’
physical addresses (on a virtual interface, not tied to a specific interface), they can swap control
of an address if the current forwarding and active router fails. But there is actually a way you
can sort of achieve load balancing with HSRP—by using multiple VLANs and designating a
specific router active for one VLAN, then an alternate router as active for the other VLAN via
trunking. This still isn’t a true load-balancing solution and it’s not nearly as solid as what you
can achieve with GLBP!
