I need to be able to connect at least 2 cisco sg300 switches together that already have fiber link back to a core switch. The 2 cisco sg300s switches at sites also have a fiber connecting each other. I need to be able to keep this fiber link active so if the core link fails then a switch can still be up on the network off another sg300. With each switch having 2 uplinks but both not going back to a core switch then I cant lag them. Is either HSRP, VRRP, GLBP the right solution or just some static routes between? Don't particularly want to reply on spanning tree to keep me from a loop. Thanks for any opinions and sample configs if possible.
