Yep, you read that correctly. Let’s use the following topology: We have two routers, R1 and R2. Chief Information Security Officer (CISO) CISSP; Advanced. The Cisco Catalyst 2950, Cisco 2960 series are typical examples of Layer 2 switches. Note: In this article, we will be focusing on IP packets although the same concept applies to other protocol packets. I set up 3 Vlans on the switch and assign ports to each. Layer 2 Multicasting Routers and Layer 3 switches have the capability to make intelligent decisions regarding multicast traffic, enabling them to create multicast trees and avoid unnecessary transmission of multicast streams. 21, which is host PC-C. 1 can ping to the cisco switch. 1 then it is definitely R1. These currently have a direct point to point connection to both our 6509 switches and have static routes with metric to either switch for load sharing. Layer 2 provides for speedy seamless handoffs for most scenarios. Traditional switching operates at layer 2 of the OSI model, where packets are sent to a specific switch port based on destination MAC addresses. 253 and now I can ping NTP server and DHCP servers fine from the switch. Cisco, Layer 2. Layer 2 switching is efficient because there is no modification to the data packet, only to the frame encapsulation of the packet. The best way to troubleshoot any networking issues is to use the OSI model and go layer. In part 2 of this topic, I will show how to configure the Switch Virtual Interfaces and IP Helper addresses on the Cisco 3750G EMI: L3Switch(config)#interface vlan 20 L3Switch(config-if)# ip address 10. Many security administrators don't think of security when it comes to Layer 2 of the network infrastructure (where switches operate), and it's one of the most overlooked aspects of network security and reliability.

However, the NetFlow records don't include the source and destination ports for the traffic. A successful exploit could. Layer 2 Addressing. Ensure that Multilayer Switch-2 can ping both of these addresses on these routers. If any devices in the Layer 2 path are transparent to CDP, the Layer 2 traceroute utility cannot identify these devices on the path. 100 - then intervlan routing will allow them to ping, since the packets will be routed between the subnets. They infact perform the functions of both Routers and Switches. If the data link layer is the one that basically defines the boundaries of what is considered a network, the network layer is the one that defines how internetworks (interconnected networks) function.
