GLBP

Hello,

I am looking to move from HSRP to GLBP on my EDGE. I have two 1G circuits with different carriers. I want to go to GLBP so we can load balance between the two. Only thing is I have never seen GLBP used before and wasnt sure if it actually load balances like it says. Thanks for you input and and caveats or knowledge of you implementing and help would be appreciated.
