Hi, I have read through a few of the posts referencing similar queries. The topology I am referencing is a V-shaped topology (dual homed to both Core/DL Switches). Just want to confirm if the requirement is to span vlan's across a pair of access switches and the access switches connect into a collapsed Core/Distribution Layer than is it more viable to have a L2 link between the DL/Core Switch? The reason I am asking this is because most of the times I prefer to have this link as a Pure L3 link. Just trying to understand what the benefit would be of a L2 link.
Also since this is a looped topology an uplink from 1 of the access switches will be blocking hence it seems that GLBP would not provide any benefit. Is that a correct assumption?
Would it better to just do a loop free U or Inverted U topology instead however in this case it seems that the link between the Access Switches (U)would have to be sized appropriately with redundancy because a failure could be a disaster. Same would be for the Inverted-U but instead of the Access the DL link would have to sized.
