Prevent Denial of Service and Man In The Middle Attacks with Dynamic ARP Inspection (DAI)
A Denial Of Service (DoS) attack is an attack where a device or service becomes unavailable to devices that need it. One attack that can lead to a Denial of Service attack is ARP Spoofing.
ARP Spoofing is when an attacker modifies the IP Address in an ARP message instead of using the real IP Address of their machine. If this ARP message makes its way to other systems, it can cause their ARP Tables to be populated with bad IP Address to MAC Address bindings. This is known as ARP poisoning.
Dynamic ARP Inspection (DAI) is designed to prevent ARP Spoofing and can keep your systems from having their ARP Tables poisoned.

How To Configure A Leak Map | EIGRP Protocol
Просмотров 3412 года назад
Watch this tutorial and learn how to configure a leak map in EIGRP In EIGRP, we have the option of doing Summarization on any router in the network. When we configure summarization, all prefixes that make up the summary are suppressed. This means those prefixes are not advertised, and the peer will only be given the summary route. In certain situations, we may want to configure summarization, b...

Spanning Tree Protocol: What Is Multiple Instance Spanning-Tree?
Просмотров 4582 года назад
You probably know about Common Spanning Tree (CST), Rapid Spanning Tree (RSTP), Cisco Per Vlan Spanning-Tree (PVST), and Cisco Rapid Per VLAN Spanning-Tree (PVST ). But there's another mode of spanning-tree you can run on your switches, and that's Multiple Instance Spanning-Tree (MST). This video will discuss the basics of Multiple Instance Spanning Tree. By the time you finish this video, you ...
PVST, PVST+ and Spanning-Tree Convergence
Просмотров 1,1 тыс.3 года назад
Cisco has their own implementation of Spanning-Tree, which is Per VLAN Spanning-Tree. It's different than the IEEE Standard, and you're expected to understand it for your CCNA exam. It's also important to understand how Spanning-Tree converges when there is a link failure in the network. Understanding this will help you understand why we prefer PVST over PVST. Studying for your CCNA exam? Looki...

    What's the point of not assuming both ports on a segment alternate (blocked)? Keeping one of them as Designated seems useless, because it forwards traffic to a blocked port and it always gets dropped. (Talking of STP 802.1D)

    In Eigrp don't use Wildcard mask. We can use Simple Subnet mask 🤨

    • @kofibonsu8466
      @kofibonsu8466 3 месяца назад

      EIGRP uses wildcard mask, but if you do not specificy it-it automatically defaults to classful addressing. You might want to use wildcard if you do not want some networks being advertised...
