BGP community criteria

community	latency
(64511, 1)	(0, 2.7ms]
(64511, 2)	(2.7ms, 7.3ms]
(64511, 3)	(7.3ms, 20ms]
(64511, 4)	(20ms, 55ms]
(64511, 5)	(55ms, 148ms]
(64511, 6)	(148ms, 403ms]
(64511, 7)	(403ms, 1097ms]
(64511, 8)	(1097ms, 2981ms]
(64511, 9)	> 2981ms
(64511, x)	[exp(x-1), exp(x)] ms (for x < 10)

community	latency
(64511, 21)	>= 0.1mbit
(64511, 22)	>= 1mbit
(64511, 23)	>= 10mbit
(64511, 24)	>= 100mbit
(64511, 25)	>= 1000mbit
(64511, 2x)	>= 10^(x-2) mbit

bw = min(up,down) for asymmetric connections

community	crypto
(64511, 31)	not encrypted
(64511, 32)	encrypted with unsafe vpn solution
(64511, 33)	encrypted with safe vpn solution (but no PFS - the usual OpenVPN p2p configuration falls in this category)
(64511, 34)	encrypted with safe vpn solution with PFS (Perfect Forward Secrecy)

Propagation:

• for latency pick max(received_route.latency, link_latency)
• for encryption and bandwidth pick min between received BGP community and peer link
