Solved: Use GLBP + HSRP on one Router

jeffland_98 · ‎03-02-2010

We are currently using GLBP on two routers to load balance the lan traffic between them. However we would like to have one subnet alway use a specific router so it will use a specific route to a backup site. Is it possible to remove that subnet from GLBP and use HSRP on that subnet alone to ensure it will use the specified router except in the case of a loss of the router? Has anyone tried this? Thanks.

You can use GLBP and HSRP on the same device if that is what you want to do. Or if you do not specify a load-balancing method with the interface command "glbp load-balancing [host-dependant|round-robin|weighted] then GLBP will function as HSRP does anyway.

Edit - with no load-balancing method it is the AVG that forwards traffic.

Jon,

Thanks for the info. I went back and looked and it is in the documentation I have. I just missed it. This should do what we need.
