BGP Communities
Cloudfira supports standard and extended BGP communities for traffic engineering. Use these to control route announcements and influence traffic paths.
Informational Communities
These communities are added to routes to indicate their origin:
| Community | Description |
|---|---|
| XXXXX:1000 | Learned from customer |
| XXXXX:2000 | Learned from peer |
| XXXXX:3000 | Learned from transit |
| XXXXX:100 | Learned in Madrid |
| XXXXX:200 | Learned in Valencia |
Action Communities
Customers can attach these communities to influence announcement behavior:
| Community | Action |
|---|---|
| XXXXX:0 | Do not announce to any peer or upstream |
| XXXXX:1 | Prepend 1x to all |
| XXXXX:2 | Prepend 2x to all |
| XXXXX:3 | Prepend 3x to all |
| XXXXX:9000 | Blackhole route |
Large Communities
We also support RFC 8092 large communities for more granular control:
| Community | Action |
|---|---|
| XXXXX:0:peer-asn | Do not announce to specific peer |
| XXXXX:1:peer-asn | Prepend 1x to specific peer |
| XXXXX:2:peer-asn | Prepend 2x to specific peer |
Note: Replace XXXXX with Cloudfira's actual ASN. Contact your account manager for the current ASN and any custom community requirements.
