SW-1 is a Layer 3 switch; SW-1 has the command SW-1(config)#ip routing applied on to it; Explanation of certain terms. 1. SVI - Switched virtual interface - Example: Interface VLAN 10. These are virtual interfaces that are created by the IOS; These act as "connecting points" & allow "connectivity" to switch IOS

Layer 3 Ethernet switch is still only capable to route between Ethernet segments (with different subnets), whereas a router is capable of changing the datalink layer encapsulation of the IP packet. It could route between Ethernet, Serial, POS, FDDI etc.

When i log on to a swtich and i want to know if this is a Layer 2 or Layer 3 switch is simply issue the command. show run | i gateway. Layer 2 mode devices are typlically configured with "ip default-gateway <next hop> However, if you want to know if your swtich would support Layer 3, then you can fall back on the already posted messages . Thanks

Hello Team, I would like to use a Layer 3 switch as my gateway between my LAN and the ISP. I discovered that much as you can configure an IP address on the physical interface of a switch when it is running on Layer 3 mode, you cannot apply command of " IP nat inside" or "IP nat outside" on the Interface configuration mode.

Simply put, any switch that supports routing regardless if it's static routing or dynamic can be classed as layer 3 switch. Besides this, any thing that routes b/w subnets is a router essentially. SO L3 switch as many expert says is just a marketing terminology that switches as …

As i tested, a 2960 switch can work as a layer 3 switch and support ip routing and enter VLAN routing and ip route commands and so on if you enable layer 3 functioning on them by 2 simple commands 1. Sdm prefer lanbase- routing 2. ip routing.

I'm trying to configure OSPF routing on a network that includes Layer 3 switches and routers. I've got the routers communicating, however the switches are not.The switch ports have been given IP addresses, and I've set up OSPF routing on them, advertising the attached networks.

The bit I wasn't sure about was the link between the layer 3 switch and the router. On the layer 3 switch end of the link I set it as an access port as part of VLAN 50, as you need to assign it to some vlan on a layer 3 switch. On the router end of the link though I just assigned the IP address to the physical interface.

So I've got a 2960 switch in packet tracer and upgraded the IOS to 15.0(2)SE4. It now accepts the 'sdm prefer lanbase-routing' command, but after a reload I still can't issue the 'ip routing' command. The OCG indicated that the 2960 provides layer 3 routing. Is this a packet tracer thing or is the 2960 not in actual fact a layer 3 switch?

you would need to create whats called a Switch Virtual Interface (SVI) on the layer 3 switch in order for the two devices to communicate. An SVI is a logical layer 3 interface on a multilayer switch that can provide Inter-VLAN routing ability. Now, just to mention here, you are using the same subnet on each VLAN.
