What are some of the advantages of router-on-a-stick inter VLAN routing?
The Many Benefits of Router-on-aStick
- shaping traffic between VLANs.
- segmenting traffic with more granularity than simple access rules that most switches can provide.
- scanning traffic between networks for malware or spyware, or any other.
- packet monitoring.
What distinguishes traditional routing from router-on-a-stick?
Traditional routing requires a routing protocol, whereas a router-on-a-stick only needs to route directly connected networks. Traditional routing uses one port per logical network, whereas a router-on-a-stick uses subinterfaces to connect multiple logical networks to a single router port.
Which configuration is required for configuring a router-on-a-stick?
Design & Configure A router on a stick is one of the ways to allow routing between VLANs. That kind of a setup consists of a router and a switch connected through one Ethernet link configured as an 802.1q trunk link. Such a configuration is typical in networks where no layer-3 switch exists.
Can you use inter VLAN routing with router on stick topology?
Inter VLAN Routing with Router on Stick topology can be done for the VLANs on Layer 2 or Layer 3 switches. But here, there is a single Layer 3 device, a router or a multilayer switch is required at the top. For its configuration steps, it is an easy way but for security perspective, single router at the top means also, single point of failure.
What do you need to know about intervlan routing?
SW1 has two VLANs so we have two different subnets. If we want communication between these VLANs we’ll have to use a device that can do routing. In this example we’ll use a router for the job. R1 will need access to both VLANs so we’ll create a 802.1Q trunk between SW1 and R1.
How to configure a router on a stick?
Router (config-subif)#encapsulation dot1q 20 (Assigning the sub-interface port f0/0.2 to VLAN 20. Here, 20 is the VLAN number)
What’s the difference between Inter VLAN and trunk router?
Unlike the traditional inter-VLAN routing method, router-on-stick does not require multiple physical interfaces on both the router and the switch. Instead, the router’s operating system makes it possible to configure the router interface to operate as a trunk link, which is then connected to a switch port that is configured in trunk mode.
