I have also issued a PR on the BGP communities draft, with some nits, feel free to review:

https://github.com/luismcontreras/alto-bgp-communities/pull/1/files

Luis, would you be able to check the following sentence? I think I understand what is trying to say, but it seems a bit confusing, thanks:

"BGP Communities can be useful for indicating local preferences for a route to the receive to a set of IP prefixes in a peering scenario"

B/R,
Jordi

Hi ALTOers,

Luis and Jensen have revived these two drafts in prep for the next interim meeting:

https://github.com/luismcontreras/alto-bgp-communities
https://github.com/alto-wg/draft-alto-bgp-ls

I have also made some suggestions to the draft-alto-bgp-ls via this pull request, feel free to review: https://github.com/alto-wg/draft-alto-bgp-ls/pull/2/files

Thanks,

Hi Authors,



We identifies these two drafts as two deployment catalysts that may ease the integration of ALTO in operational networks. We would appreciate if you can revive these two drafts and circulate them in preparation to the future ALTO interims. Thank you.



Cheers,

Qin & Med
