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:*

Country	ISO 3166-1 numeric format	BGP Community	BGP Extend Community	BGP Large Community
Thailand	764	65100:764	RT:65100:764	63529:1900:764

City	ID	BGP Community	BGP Extend Community	BGP Large Community
Bangkok	1	65101:1	RT:65101:1	63529:1901:1
Chiang Mai *	2	65101:2	RT:65101:2	63529:1901:2

Site	ID	BGP Community	BGP Extend Community	BGP Large Community
Bangna Data Center (BNDC)	1	65102:1	RT:65102:1	63529:1902:1
CSL CW	2	65102:2	RT:65102:2	63529:1902:2
BKNIX CMI1	3	65102:3	RT:65102:3	63529:1902:3
NTT BKK2	4	65102:4	RT:65102:4	63529:1902:4
AIMS DC TH	5	65102:5	RT:65102:5	63529:1902:5

Therefore, all prefixes in BKNIX Route server will be tagging with multiple communities representing geological location where those prefixes were received based on the table below
