Hi All,

In scaled EVPN deployments it can be wise to name ESI that way to represent the site/physical port/etc it is attached to. Thus on some remote location you can easily verify where particular route/MAC is coming from. Similar to phone numbers, where you can locate the country/area/possibly a company of the caller. Thus we identified couple of ideas for it. That should ease support and structure deployments or new site integrations.

Q.
What is the best practice creating ESI?


A.
That is flexible however we can propose choosing smth like:

Variant 1:

aa.aa.aa.XX.XX.YY.YY.ZZ.ZZ

  • ZZ.ZZ = Bundle ID 7777
  • YY.YY = rack number
  • XX.XX = Site ID

Example:

evpn

interface Bundle-Ether1177

  ethernet-segment

   identifier type 0 aa.aa.aa.03.33.11.22.11.77

 

Variant 2:

10.00.00.XX.YY.00.00.ZZ.ZZ

 

Where:

XX = REGION

YY = DC Number from Router Target in VRF Identifier

ZZ.ZZ = Bundle-Ethernet ID

 

Example:

10.00.00.12.01.00.00.77.77

 

P.S. Let us know your thoughts and ideas on how to do it better.
