PoP Codes

Point of Presence (PoP) codes used in AS203314 BGP communities for location-based routing.

Each Point of Presence (PoP) has a unique 3-digit code used in community strings like 203314:120:XXX and 203314:202:XXX.

Usage: These codes identify specific PoP locations in internal communities (120:XXX, 125:XXX) and control communities (202:XXX).

Identify where a route was learned:

203314:120:101  → Learned at HKG1 (Hong Kong)
203314:120:131  → Learned at TYO2 (Tokyo)
203314:120:302  → Learned at IAD (Ashburn)

Exclude specific PoPs from receiving announcements:

203314:202:301  → Do not announce via Seattle
203314:202:131  → Do not announce via Tokyo
203314:202:102  → Do not announce via HKG2

Tip: PoP codes are primarily used for granular traffic engineering when you need to control route propagation at the location level.
