What's the difference between layer 3 switches and routers?
Routers are used in the WAN environment. Router never forward broadcast traffic but switch does. The primary difference is with feature set support, hierarchical design and WAN interfaces. The purpose of layer 3 switches is aggregation and high speed packet forwarding between servers local to the data center.
Fundamentals of Operations on a Layer 3 Switch - Cisco Learning …
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. If the switch IOS is routing capable, then these act as a "connecting point" to that "router".
Help configuring OSPF on a Layer 3 switch - Cisco Learning Network
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. However, no adjacencies are forming.
What are the differences between Layer 2 and Layer 3 ports?
This is my thinking: A Layer 2 port uses physical addresses and is used for communicating between devices on the same IP network. It is used for switching and can't be used to send data to other IP networks. A Layer 3 port uses logical addresses and is used for communicating between devices on different IP networks. It is used for routing.

Packet Tracer - Connecting routers to Layer 3 Switches
I have here a network with a layer-3 switch at the middle. I was planning to use the same method in the previous discussion, but I am doubtful on what IP address I should assign. Here's a screenshot and I'll attach my current work and an Excel file. The red circles are the routers with their IP address configured, except for Ethernet.
Devices are not getting DHCP over Layer3 etherchannel link
3. Vlan 1 interface has an "ip helper-address" configured on it that points to the ip address of your router that hands out DHCP. 4. Your layer 3 etherchannel has a /30 network connecting the two devices. 5. Switch 1 has a static route pointing to the /30 router ip address nearby. 6. Switch 2 has a static route pointing back to the /30 switch ...
Layer 3 VPC in Nexus - Cisco Learning Network
You can do Layer 3 over vPC depending on the code and model of your switches. 7Ks for example require F2E, F3 or M3 line cards to support it while 9Ks need to run at least 7.0(3)I5(1). Refer to the Technote for more info.
