GLBP Check

I have setup GLBP to replace HSRP on my two host routers. However, they do not appear to be load balancing when I look at my network monitoring. All outbound traffic is using only one router. Can someone take a look at my configs listed below and see what I might be missing. I've also included the "show glbp" results from the two routers. Thanks.

Who is a "client" for the GLBP? Do you have a single device who connects to these two routers? Then it will never work.

GLBP works only when you have multiple clients on Layer2 network. Basically, when Client1 goes to a gateway, GLBP gives MAC Address1, and when Client2 goes to the same gateway, GLBP gives secong MAC address. That's how it provides "load balancing". If you have a single client (for example, firewall), it will ask for MAC address once (through ARP), and then will use it all the time until ARP entry expires. Here is a link to Cisco, explaining how it works.
