EIGRP 'populate bgp-ext-comm' command feature

r1.Lab-Router(config-router-af)#?
populate Populate BGP Ext Comm

Someone please provide specific details about which Ext Community is being populated as well as which technology is it tied to. It could be that it is related to OTP/MTR or some other Cisco EIGRP technology/solution option but I'm having a hell of a time finding any specific details. I can find the random one line descriptions but nothing that gives me the specific details as to what I'm sharing between EIGRP and BGP. Let me know if you can help clarify and thanks in advance!

Hello,

 

It be used for a couple things with L3 MPLS VPN. See document below:

I know it transfers the EIGRP metrics to the remote side as well as SoO (Site-of-Origin) information.
