I wanted to know more about VXLAN and NVGRE so who better than Ken Duda from (http://aristanetworks.com) from Arista Networks, the only author listed on both IETF RFCS and [Ivan Pepelnjak](http://blog.ioshints.info) on a call to go fast and loose on the topics.
[IETF VXLAN](https://datatracker.ietf.org/doc/draft-mahalingam-dutt-dcops-vxlan/) [IETF NVGRE](https://datatracker.ietf.org/doc/draft-sridharan-virtualization-nvgre/)
What is VXLAN and why does networking need it ? How does it works, and what are it’s future impacts on networking ?
Comparing NVGRE and VXLAN and why there are two standards ? Why aren’t we using MPLS or LISP ? Cover some of the limitations ? What about lack of transparency with VXLAN packets ? What about L2 security challenges inside VXLAN networks ?
In particular, the key lesson I learned is that the control plane is open. The current implementation doesn’t specify the end point discovery and OpenFlow is a consideration here. And that VXLAN silicon is planned for the future for networking intervention in flows.
and last, and the very least:
