|
does not support VLAN-tagged packets

|
|
does not scale well beyond 50 VLANs

requires the use of more physical interfaces than legacy inter-VLAN routing
|
|
|
requires the use of multiple router interfaces configured to operate as access links

Detailed explanation-1: -Explanation: A router-on-a-stick design is the same as having a trunked interface between the router and the switch. This design works, but does not scale well because all VLANs must traverse the one connection between the router and the switch.
Detailed explanation-2: -The main advantage of Inter-VLAN routing is that the switch is handling the routing of traffic between the VLANs. In a router-on-a-stick setup, traffic between the VLANs would need to pass through the router multiple times (Tx and Rx).
Detailed explanation-3: -Advantages. Networks that utilise router on a stick benefit from only requiring one LAN connection to be used for multiple VLANs, i.e. the number of VLANs are not limited by the number of LAN ports available. Separation of network connections do not respond to the physical location of the ports on the router.
