Informative Communities

Applied to a prefix on ingress from a BGP session (customer, peering, or transit). May be used for routing policy within AS58511. Any given unicast route will be tagged with two communities: class (e.g. transit, peering, etc.) and region of origin (e.g. AU-VIC)

Community	Definition
58511:0	Originated by AS58511 internally
58511:1	Learned via customer
58511:100	Learned via transit (global or domestic-only)
58511:200	Learned via peering (IX; via route-servers or bilateral session)
58511:300	Learned via PNI (private network interconnect)
58511:9001	Learned in region: AU-VIC (also includes TAS)
58511:9002	Learned in region: AU-NSW (also includes ACT)
58511:9003	Learned in region: AU-QLD
58511:9004	Learned in region: AU-WA
58511:9005	Learned in region: US-WEST
58511:9006	Learned in region: NZ
58511:9007	Learned in region: EU
58511:9008	Learned in region: ASIA
58511:9009	Learned in sub-region: AU-GIPPS
58511:9010	Learned in region: AU-SA (also includes NT)
58511:10000	Learned from out-of-region source

Action communities

Can be set by customers on announcements to AS58511 to influence routing within AS58511, and announcements of customer prefixes to upstreams.

Community	Definition
58511:666	Blackhole - drop all traffic destined toward this prefix; works up to /32 IPv4 or /128 IPv6 host prefix
58511:380	Set local preference to 380 on import
58511:390	Set local preference to 390 on import
58511:400	Set local preference to 400 on import (customer default)
58511:410	Set local preference to 410 on import
58511:420	Set local preference to 420 on import

Announcement control

For transit customers, our default is to announce to all peers (internally setting community 58511:10 per below). This means that by default, announcements to all external ASes in all categories in all regions are enabled. Customers may then add any combination of the below to filter selectively who they are announced to.

See Informative Communities section for region codes to substitute in place of xxxx in the below. For example, 9001 is the code for AU-VIC. The "out-of-region" code, 10000, is also supported (e.g. 65001:10000 for "do not export to any transit out-of-region")

Community	Definition
58511:10	Export to all (default; always applied on customer ingress)
no-export	Do not export to any external AS
65001:0	Do not export to transit
65001:xxxx	Do not export to transit in region XXXX
65001:10000	Do not export to transit outside the learned-in region
65002:0	Do not export to peering
65002:xxxx	Do not export to peering in region XXXX
65002:10000	Do not export to peering outside the learned-in region
65003:0	Do not export to PNIs
65003:xxxx	Do not export to PNIs in region XXXX
65003:10000	Do not export to PNIs outside the learned-in region
65004:0	Do not export to customers
65004:xxxx	Do not export to customers in region XXXX
65004:10000	Do not export to customers outside the learned-in region
65005:0	Do not export to content caches
65005:xxxx	Do not export to content caches in region XXXX
65005:10000	Do not export to content caches outside the learned-in region
