GLBP (Gateway Load Balancing Protocol)

Once again just like with VRRP, HSRP and GLBP any of you that are using GNS3 and happen to be having trouble getting the devices to talk to one another and become active/standby and it does not work despite having layer 3 connectivity and everything being configured correctly.

You need to use the global config command:

no ip igmp snooping

This needs to be on all switches the mutlicast traffic passes through

I had to do this on IOU L2 images, show version output here:
