BGP Information
Fine-Grained Control
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).
58511:0 Originated by AS58511 internally
58511:1 Learned via customer
58511:10 Export to all
58511:100 Learned via transit
58511:200 Learned via peering
58511:300 Learned via PNI
58511:9001 Learned in region: AU-VIC
58511:9002 Learned in region: AU-NSW
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
Action Communities
Can be set by customers on announcements to AS58511 to influence routing within AS58511, and announcements of customer prefixes to upstreams.
DDoS Filtering
58511:666 Blackhole Drop all traffic destined toward this prefix (works up to/32 IPv4 or /128 IPv6 host prefix)
Localpref Control (RFC1998)
58511:380 Set local preference to 380 in import from customer
58511:390 Set local preference to 390 in import from customer
58511:400 (Default) Set local preference to 400 in import from customer
58511:410 Set local preference to 410 in import from customer
58511:420 Set local preference to 420 in import from customer
Announcement Control
Default is to announce to all peers (using community 58511:10 as per below); these communities may be used by customers to stop announcements to certain peers.
58511:10 Export to All (Default)
65001:0 Do not announce to transit
65001:xxxx Do not announce to transit in region xxxx
65002:0 Do not announce to peering
65002:xxxx Do not announce to peering in region xxxx
65003:0 Do not announce to PNIs
65003:xxxx Do not announce to PNIs in region xxxx
65004:0 Do not announce to customers
65004:xxxx Do not announce to customers in region xxxx
