How to Build an IP Fabric
Mar 28, 2014

The QFX5100 is a really great building block to build some impressive data center networks. The flexability of the platform allows you to create a traditional L2/L3 network; your choice of Ethernet Fabrics; and, of course, a carrier-class IP Fabric.

 

With the introduction of VMware NSX and Juniper Contrail, overlay networks in the data center are becoming more common. The obvious requirement being that you need to build a carrier-class IP Fabric as the foundation. The reality is that not all data center are completely virtualized and bare-metal servers are still alive and well. We'll need a method to include bare-metal servers into this new overlay architecture, regardless if you choose VMware NSX or Juniper Contrail. This functionality will translate the data plane between VXLAN to VLAN on behalf of the bare-metal server; most commonly this feature is referred to as VXLAN L2 Gateway. The QFX5100 supports VXLAN L2 Gateway and many other virtualization features.

 

So how do you get started building this IP Fabric? Check out my new white paper that walks you through step-by-step how to configure a carrier-class IP Fabric. It includes the following benefits:

 

  • Example topologies that are possible using the QFX5100 as a building block
  • 768x10GE all the way up to over 200,000x10GE using only the QFX5100
  • Best practices with BGP ASNs
  • Best practices with BGP routing policies
  • Tested and verified BGP import and export policies
  • Full Junos configurations

Have fun building your IP Fabric with the QFX5100 Cat Very Happy

Hi Doug,

 

Interesting document, I read about this O'Reilly book as well. How does this work if we don't want to use standard VXLAN flood and learn, can EVPN be an option for control plane? and how will it work with an overlay of BGP.
