Traditional Inter-VLAN Routing and Configuration
Traditional Inter-VLAN Routing Overview
Networks are perpetually evolving, and within the past few years variety of trends became apparent. initial of all, the
internet Protocol (IP) has become the Layer three protocol of selection for contemporary networks, with different Layer
three protocols like Internetwork Packet Exchange (IPX) and AppleTalk quickly being phased out. ip interconnects the
net. The increasing reliance of organizations on the net has promoted ip because the Layer three protocol of selection.
Secondly, local-area networks (LANs) have seen tremendous advances in terms of performance, bandwidth, and
lowering price. The LAN provides the medium over that users and devices connect with the interior ip network and
also the net thus is a very important part of networking. LAN topologies have evolved from historically being single, flat
broadcast domains into multi-virtual LAN (VLAN) topologies, with inter-VLAN routing needed to modify
communications between every VLAN. Multiple VLANs increase network potency by reducing broadcast domain size,
still as providing a mechanism to permit network layer access control to be applied between VLANs. using multiple
VLANs additionally means the resiliency of the network depends less on Layer two protocols like Spanning Tree
Protocol (STP), and additional upon Layer three routing protocols. trendy Layer three routing protocols are far more
intelligent than standard pressure and as a result will converge far more quickly within the event of a network failure.
Finally, segmenting a LAN network into VLANs permits for the isolation of issues to a smaller segment of network,
allowed for low-impact on the network and easier fault finding.
All of the on top of factors have caused the wants for inter-VLAN routing at intervals LAN networks to soar over the
past few years. although this book is primarily regarding switches, that area unit historically Layer 2-only devices, it’s
vital to know the fundamentals of inter-VLAN routing. Possessing this information helps you to know Layer three
switches, that are getting cost-efficient, high performance alternatives to ancient routers for routing ip traffic between
LAN segments. Possessing a elementary understanding of inter-VLAN is very important if you have to design
multilayer typologies that are stable, available, and scaleable.
