When STP is first enabled on a switch, it assumes that it is the root bridge and begins broadcasting BPDU (Bridge Protocol Data Unit) messages to other switches. Each switch that receives the BPDU message compares the bridge ID of the sending switch with its own bridge ID. The switch with...
SPAN/ERSPAN, improved server device, ... Internet Of Everything features, sensors ans programmig languages is the main improvement of this new version which become a good network simulator for prepaing the new CCNA Industrial exam.
My suggestion for CCNA you don't need to go so deep. But for you is good to know for what for is port priority in STP election, default value and which value is more preferred. I hope now that you understand how the values are formed. Good luck in the world of networking! LikeRepl...
With STP, only one link is active and the other links are blocked. Improved Scalability – In the event of oversubscription, we can add a spine switch and connect it to every leaf switch. If the port density is a concern, we can add a leaf switch and connect it to every spine switch...

CDP is one of the protocols, that are always sent in VLAN 1 (even if VLAN 1 is not the native VLAN). Also VTP and PaGP are always sent in VLAN1 while STP and DTP will always be sent in the native VLAN (i.e. untagged). See here for a discussion about that: Are CDP and VTP...
An Intranet is a private internal network, often used by organizations to provide employees with shared resources. With an Intranet, computers are connected to an internal, private network (e.gLAN network) that is not typically accessible via the internet. Many intranets are set up locally, with...

The Bridge Priority (Switch Priority) value is used to find the Bridge ID (Swtich ID). The Bridge ID (Swtich ID) is made from two values. •The Switch Priority, which is a numerical value defined by IEEE 802.1D, which is equal to 32,768 by default. ...
802.1q is the trunking protocol covered for inter-VLAN traffic. Spanning tree protocol (STP) is covered in ICND part 1. The need for redundancy in LANs causes looping, and STP is the protocol that prevents routing loops. Final Thoughts Overall, this course gives you great exposure to the ...
