Location tagging

BKNIX Route servers offer set of BGP communities indicating which location the prefix was learned from BKNIX platform.

Currently, we tag these communities which specific scope of locations below

Country Level : apply ISO 3166-1 numeric format eg. Thailand
City Level : apply infrastructure id corresponding main city
Site Level : apply BKNIX site ID

Note that BKNIX will stipe out these set of BGP communities (if any) and then set these communities again to maintain the accuracy of information.

       BGP Community : 65100:*, 65101:*, 65102:*
       BGP Extended Community : RT:65100:*, RT:65101:*, RT:65102:*
       BGP Large Community : 63529:1900:*, 63529:1901:*, 63529:1902:*
