See RFC 6313, Figure 1.)<br> <br> eg, the BGP community draft referenced below creates a new bgpSourceCommunityList. I suppose this may be a list of bgpSourceAsNumber, but that's not specified in the draft - so it could equally be a list of sourceIPv4Address or any other IE.<br> <br> Alternatively, devices could simply export IE #291 (basicList), with the bgpSourceCommunityList and bgpDestinationCommunityList disambiguated by the basicList Field ID contained in the basicList header.
