Inter Vlan Routing Layer 2 Switch

Host all the vlan svis the 254 addresses on one of the switches enable ip routing to allow intervlan routing and use a trunk to connect the two switches ensure the layer 2 vlans are configured on both switches and the vlans are permitted across the trunk.

Inter vlan routing layer 2 switch. Note that i have published a similar scenario in the past which depicts how to implement inter vlan routing using regular ios switches in the article here. This is known as inter vlan routing. Interface vlan175 ip address 1017501 2552552550 no shutdown. Vlan10 and vlan20 with ip address 10101010 and ip address 10202020.

2315 packet tracer configure layer 3 switching and inter vlan routing packet tracer configure layer 3 switching and inter vlan routing answer version answer note. In figure 2 layer 3 switch is configured with ip address 10001. On a layer 2 switch like the cisco catalyst 29502960 we also have a svi but you can only use it for remote management. Vlans divide broadcast domains in a lan environment.

The document uses a catalyst 2950 series switch and a catalyst 2948g switch as layer 2 l2 closet switches that connect to the catalyst 3550. Hi all please help im trying to implement inter vlan routing router on a stick between two private networks using a layer 2 catalyst 2950 switch running iso 123 and a cisco 2801 router. In router on a stick method both switch and router are needed but while using layer 3 switch a single switch will perform inter vlan routing as well as the layer 2 functions vlan therefore this method is cost effective and also less configuration is needed. Topology addressing table device interface ip address subnet mask mls vlan 10 19216810254 2552552550 vlanread more.

Next step is to create a svi for vlan 10 and 20 and configure ip addresses on them. On catalyst switches it is accomplished by the creation of layer 3 interfaces switch virtual interfaces svis. The document provides a sample configuration for intervlan routing with a catalyst 3550 series switch that runs enhanced multilayer image emi software in a typical network scenario. This configuration might look familiar if you worked with layer 2 switches before.

If you forget this your switch wont build a routing table. The layer 3 switch could be used as a router. The example below will explain how to configure layer 2 vlans layer 3 switch virtual interfaces and layer 3 inter vlan routing using nexus switches. The hosts connected to each vlan would use the svi on the layer 3 switch for it vlan as the gateway.
