FabricPath is Layer 2 routing, also known as MAC-in-MAC routing. This is achieved by running IS-IS protocol in the L2 control plane, where it is responsible for building the topology and Shortest Path Tree (SPT). Routing protocols for the win!

FabricPath was designed to overcome the limitation of Spanning-Tree Protocol (STP)
With FabricPath, we have the capability to actively forward on all links. If there is a failure on one of the links, traffic will be redistributed across all the others. When traffic comes into the FabricPath domain, a single lookup is performed to identify the switch closest to the destination, providing optimal flows.

We're all cut from the same cloth, or in other words, fabric. It only makes sense that we connect with each other in the most immediate way, with all lines of communication open and inviting. In th...

Cisco DC :
Spanning-tree Bridge Assurance
One Command Can Achieve These Features :
- STP enhancement to help prevent against unidirectional links
- Automatically prune unneeded VLANs from trunk links
Bridge Assurance is configured by setting the spanning-tree port-type network at the link level

NAS vs SAN
The primary difference between NAS and SAN solutions is the type of access protocol. NAS protocols such as NFS and CiFS provide shared file level access to storage resources. The management of the file system resides with the NAS device. SAN protocols such as iSCSI and fibre channel provide block level access to storage resources. Block level devices are accessed by servers via the SAN, and the servers manage the file system.
Despite their differences, SAN and NAS are not mutually exclusive, and may be combined in multi-protocol or unified storage arrays, offering both file-level protocols (NAS) and block-level protocols (SAN) from the same system. The best of both worlds!
Benefits of NAS
• NAS devices typically leverage existing IP networks for connectivity, enabling companies to reduce the price of entry for access to shared storage.
• The RAID and clustering capabilities inherent to modern enterprise NAS devices offer greatly improved availability when compared with traditional direct attached storage.
• Because NAS devices control the file system, they offer increased flexibility when using advanced storage functionality such as snapshots.
• With 10GE connectivity, NAS devices can offer performance on par with many currently installed fibre channel SANs

A Friend Asking :
Why Im Spending Long Day on Configuring a Router ! (7604 PE ) .
Answer :
Life isn't GNS3 only for sure smile emoticon .
- Power Standard Arrangements ( American - British ) , if u Electronic, Electrical, Computer or Telecom Engineer u should understand how to arrange between American & British Types of power & differences between them .
- IF you prepare a complete Rack , you should understand the Wattage Consumption to be sure the control panel can handle your Amber and Voltage.
- Modules Installation and Configuration ( isn't choose and Select like GNS3 )
- Understanding and preparing the differences between Internal / External flash memory and how to manage your boot options to prepare the IOS.
- Understanding the difference between Route Switch Processor (RSP) and
Supervisor Engine (Sup) and prepare them to be functional .
- Understanding Fiber Optics to Choose the Suitable components to be functional .
- Then Start Configuring the Network with MPLS, VPNv4, IGW, VRF and Other Required Solutions .

معلومه SP
احد افكار ال L2VPN هيه EoMPLS ..
ميزة هذا السيناريو الاولى عملية ال Bridging ...
لكن الميزة الكبرى في سيسكو ايضا ومن النادر العمل بها .. هيه انك ممكن تشتغل بنفس ال Concept .. على الانترنت ولا تحتاج Core MPLS نهائيا ... تقدر تعملها على DMVPN or GRE Over IPSEC Tunnel ...
والميزة الاكبر ايضا .. الذين يتعاملون مع QinQ بكثره .. من المتعارف عليه ان ال QinQ يحتاج L2 Core Network ... لكن باستخدام ال L2VPN تقدر تعمل QinQ على L3 Core Network ...
ياريت مواضيع مثلا هذه تتضمن ضمن كورسات ولو حتى CCIE R&S or SP
وان كانت معلومات معقده للبعض .. سأشرح لاب عن قريب .
المعذره عن التأخير في سلسلة الفيديوهات للتحضير لل CCIE
