As I underatand it, the only qualitative difference between HSRP and GLBP is that GLBP offers load balancing by allowing all routers in a GLBP group to forward traffic, unlike HSRP, where you have an active router and the other is in standy.
So, I saw some client configs on a few of their routers, where they have GLBP configured instead of HSRP, but then they have load balancing shut off with the "no glbpp load balancing" command.
Im thinking to myself "why would they do that"? Why not just use HSRP and be done with it? Without GLBP's load balanacing feature, what qualititative difference is there?
