For a Dual core campus LAN design, we know that HSRP or GLBP will give the router redundency. with one of them enabled on distribution switches for a switch block, if one Ethernet link between one access switch and distribution switch failed ( say disconnect)how will that access switch forward its frames to the standby router
as it will not become active even this link fail? At normal operation do these switches forward its frames using both redundant links or do they use only the link to the currently active gateway??
