End-to-End VLANs
End-to-end VLANs is a single VLAN that is associated with switch ports that are widely dispersed throughout a campus network often in multiple switches (Frahim & Froom, 2015). In most instances, this VLAN is geographically dispersed throughout the network. This is to mean that users are grouped into each VLAN irrespective of their physical locations. As users move throughout the enterprise, the VLAN connection of that user remains the same. This is an implication that end-to-end VLAN does not operate basing on the location of the switch attached to the user. One of the most significant advantages of end-to-end VLAN is its ability to group users. Users can be convened on a common IP section regardless of their geographic locations. Secondly, network security is assured under end-to-end VLAN (Shabeeribm, 2013). This is because it contains resources that should not be accessed to all users on the network by confining the resources.
Local VLANs
Local VLANs are locally attached to a single access switch. Unlike end-to-end VLANs, local VLANs users are grouped into a single VLAN by considering their shared geographic switches (Al-Khaffaf, 2018). This is an implication that if users move from one location to the other in the enterprise, their connection adjusts to the new VLAN at the new physical location. Therefore, the local VLAN administrator should create a network by considering physical boundaries instead of the job undertaken by users on end. Thus, this VLAN exists amid the access and circulation levels. The basic advantage of this VLAN is the ability to allow easy incorporation of new features as influenced by design. Its design permits integration of new switches and also the addition of new structures if there is a need. Secondly, its limited failure area ensures that there are finite failures. This is because if the VLANs are locally attached to a switch block, and the number of devices regulated, cases of failure can be easily confined to few users.
