What is Cisco FabricPath?

Cisco FabricPath is an innovation in Cisco NX-OS Software that uses routing principles to allow Layer 2 scaling in a way that was not possible before. This technology provides the flexibility and the performance required to make data centers a service for the applications that use them.

What is the benefit of FabricPath?

FabricPath is Cisco proprietary and works in the same way as TRILL that is an IETF standard. The biggest advantage of FabricPath is that it gives us the flexibility along with loop free connectivity that STP couldn’t do and is therefore run in Data Centers as a replacement of Spanning Tree Protocol.

Which protocol is used in FabricPath technology?

FabricPath uses the IS-IS routing protocol. It supports multi-area design, and is not dependent on IP. Fabricpath is a Cisco proprietary protocol, found on some of the Nexus switch range, such as the N5K and N7K. Fabricpath is not supported on the N3K or N9K series.

What is difference between VLAN and VxLAN?

The main difference is that VLAN uses the tag on the layer 2 frame for encapsulation and can scale up to 4000 VLANs. VXLAN, on the other hand, encapsulates the MAC in UDP and is capable of scaling up to 16 million VxLAN segments.

What is VxLAN Cisco?

VXLAN is a solution to support a flexible, large-scale multitenant environment over a shared common physical infrastructure. The transport protocol over the physical data center network is IP plus UDP.

Does VXLAN require MPLS?

And MPLS VPN is supported on E2E links while Only VTEPs are required to support VXLAN.

Why would you use VXLAN?

VXLAN technology allows you to segment your networks (as VLANs do), but it provides benefits that VLANs cannot. Here are the most important benefits of using VXLANs: You can theoretically create as many as 16 million VXLANs in an administrative domain (as opposed to 4094 VLANs on a Juniper Networks device).
