Before we understand what is routing and how it works, we need to know about router. Router is a network hardware device that is used to connect two different networks. It works on layer 3 (network layer). The primary function of a router is- to...
Since static routes are manually configured and do not require advertising or processing of route updates, they use less bandwidth and fewer CPU resources on the router. This can be particularly advantageous in environments where router performance...
Each routing protocol selects the best route using its own metric comparison procedure. If there are more than one candidate routes from different protocols, then administrative distances are compared and only one protocol installs its route into...
Many Cisco APs can operate in either autonomous or lightweight mode, depending on which code image is loaded and run. From the WLC, you can also configure a lightweight AP to operate in one of the following special-purpose modes:
Cisco Wireless Architecture and AP modes connect a wireless network to a wired network to safely transfer data. A Cisco Access Point (AP) is configured to operate in either Lightweight mode or Autonomous mode. A Cisco LAP is part of the Cisco...
Routers route IPv4 packets. That simple statement actually carries a lot of hidden meaning. For routers to route packets, routers follow a routing process. That routing process relies on information called IP routes. Each IP route lists a...
AAA, RADIUS, and TACACS+ are all related to network security and access control. To access network device there are central access methods. Let’s dive into these access methods. AAA AAA (Authentication, Authorization, Accounting) Access...
Let’s dive into how to configure STP on switch. We will also look into how STP topology change occurs, what happens when link failure happens and how to protect STP. STP Topology Changes An STP topology change will occur under two...
Spanning Tree Protocol (STP) allows Ethernet LANs to have the added benefits of installing redundant links in a LAN, while overcoming the known problems that occur when adding those extra links. Using redundant links in a LAN design allows the LAN...
Upgrading Cisco Firepower Management Center (FMC) can significantly enhance your network security capabilities. Whether you’re looking to patch vulnerabilities, gain new features, or improve performance, here’s a simple guide to help you...
