Router-on-a-Stick Inter-VLAN Routing and Configuration
Overview
As mentioned within the last section, the router-on-a-stick design has physical limitations based mostly upon a fanatical
physical interface being needed for every VLAN. This limitation are often removed by exploitation trunk interfaces,
wherever multiple VLANs are supported on one physical interface by exploitation tagging technologies like 802.1Q or ISL.
using exploitation physical interfaces to connect the router to every VLAN, virtual or logical interfaces are wont to attach
the router to every VLAN.
Virtual interfaces (rather than physical interfaces) are wont to connect the router to every VLAN. one physical trunk
interface transports labeled VLAN traffic to the router, with the tag decisive to that virtual interface a frame ought to be
forwarded for routing. aside from the variations between exploitation physical interfaces per VLAN as hostile virtual
interfaces per VLAN, this design is basically clone of the normal router-on-a-stick design and suffers constant
performance limitations, as a result of the routing engine continues to be software-based and also the trunk interface is
proscribed to 10 Mbps, 100 Mbps, or 1 Gbps
