networking and their Routing protocols with commands along with diagram ,(rip, IGRP and OSPF and BGP ) and knowledge about Network devices like Router and Switch. network define and definitions of Lan, router and all the routing protocols and their features.
Spanning Tree Protocol (STP) is standardized as IEEE 802.1D.
Is a network protocol that ensures a loop-free topology for any bridged Ethernet local area network.

Presentation about interior gateway routing protocol EIGRP which covers most of the concepts and features of the protocol.
Delivered by Dmitry Figol, CCIE R&S #53592.
This tutorial gives very good understanding on CCNA Dynamic Routing Protocols.After completing this tutorial,You will find yourself at a moderate level of expertise in knowing Advance Networking(CCNA)
This slide contains concept about MPLS_VPNs specially L3_VPN protocol, according to the latest version of Cisco books(SP and R&S) and i taught it at IRAN TIC company.
In the next slide, i prepare title about MPLS L3_VPN Services and VPLS (MPLS L2_VPN)

he Associate level of Cisco Certifications can begin directly with CCNA for network installation, operations and troubleshooting or CCDA for network design. Think of the Associate Level as the foundation level of networking certification.

2. Outline
• Overview
• Functions of Ethernet Switches and Bridges
• Frame Transmission Modes
• How Switches and Bridges Learn Source MAC
Addresses
• How Switches and Bridges Forward and Filter Frames
• Summary
3. Ethernet Switches and Bridges
• Address learning
• Forwarding based on the learned addresses
• Loop avoidance
4. Transmitting Frames
Cut-Through Store and Forward
• Switch checks destination • Complete frame is received and
address and immediately checked before forwarding
begins forwarding frame
Fragment-Free
• Switch checks the first 64 bytes,
then immediately
begins forwarding frame
6. Learning Addresses
• Station A sends a frame to station C.
• The switch caches the MAC address of station A to port E0
by learning the source address of data frames.
• The frame from station A to station C is flooded out to all
ports except port E0 (unknown unicasts are flooded).
7. Learning Addresses (Cont.)
• Station D sends a frame to station C.
• The switch caches the MAC address of station D to port E3 by
learning the source address of data frames.
• The frame from station D to station C is flooded out to all ports
except port E3 (unknown unicasts are flooded).
8. Filtering Frames
• Station A sends a frame to station C.
• The destination is known; the frame is not flooded.
9. Filtering Frames (Cont.)
• Station A sends a frame to station B.
• The switch has the address for station B in the MAC
address table.
