Oct 7, 2008 · There used to be very clear differences between a switch and a router (layer 2 vs layer 3, forward in hardware vs forward in software, etc) but with the introduction of layer 3 switches the differences get smaller and smaller.

Mar 1, 2013 · Layer-2 (VLAN) traffic doesn't know or care about layer-3. You can run many different layer-3 protocols (e.g. IPv4, PIX, IPv6, AppleTalk, etc.) on your layer-2 VLAN, and the layer-2 switching doesn't care or know which layer-3 protocols are in use.

Nov 19, 2005 · Layer 3 switches are mainly used for local inter-VLAN routing; replacing a router with a Layer 3 switch is going to pose a problem, because the Layer 3 switches do not have e.g. serial ports. But the latest generation of routers, e.g. the 2800 series, have switching modules that let you integrate the switching functionality in the router.

Feb 13, 2018 · So i have been thinking, which is preferable supposing all required hardware are available for both. Configuring router on a stick or configuring inter vlan routing on a layer 3 switch.

Jul 31, 2008 · What is the decision criteria for selecting a layer-3 switch vs a Router? Is there any document that gives comparison. OK.. I will be more specific. I am planning to upgrade a 3825 router to a 7206 VXR NPE-G1 or to a 3845 ISR OR even a layer-3 switch. Reason being this router would support addition...

Mar 21, 2018 · What is the advantage of Layer 3 switch over the Router ??

Sep 9, 2012 · Hi, If the switch capable of doing layer-3 and not just layer-2, than you can configure all SVIs on the switch and have the switch route between the vlans for you. In this case since all the vlans are terminated at the switch, you need to …

Feb 19, 2016 · Hello, Maybe you can help me to compare the routing-performance between some Cisco router and layer-3-switches. I have the following example: - Cisco 3850 (WS-C3850-24T-S) vs. Cisco 1811 ISR In the data sheets you can normally see no values for routing-performance in mbbs (mega bits in seconds). O...

Mar 6, 2019 · A layer 3 switch is basically a router (albilty to have very fast and with a bunch of ports). layer 3 means its capable of routing between vlans and able to join eigrp, rip and things. you can make any of the ports on the switch a routed port. this means you can use a layer3 switch exclusively as a router if you wanted to.

The line between firewall and gateway (aka router) continues to get blurred. Each device advances to include the others features. However, fundamentally, a routers job is to route packets whereas a firewalls job is to inspect and control connections through the device.
