Communities
All peers to Balkan Internet Exchange route servers can use communities to control incoming and outgoing information.
In relation to the incoming traffic (which announces are accepted) the control is in the client – he can filter which ones of the received from RS announces he will accept.
Balkan-IX RSs remove its own AS from the route, which will make them seem directly connected without a necessary BGP session between them.
With the help of BGP Community Balkan-IX member may decide who he wants to “give” the traffic to. The following BGP Community is maintained for every announced prefix.
Communities coming from Balkan Internet Exchange RS:
0:<peer AS> | Prefix is announced from ‘<peer AS>’ |
59900:1002 | Prefix is announced from Bulgarian peer |
59900:1003 | Prefix is announced from Romanian peer |
59900:1004 | Prefix is announced from Macedonian peer |
59900:1005 | Prefix is announced from Serbian peer |
Communities that are accepted from Balkan Internet Exchange RS:
By default all incoming prefixes are announced to all Balkan-IX members, if they do not have BalkanIX specific community – 59900:.*.
59900:0 | Block Your prefix to all peers |
59900:0 59900: | Block Your prefix to all peers EXCEPT |
59900: | Block Your prefix to |
BGP communities for traffic management to providers:
59900:100 | DE-CIX |
59900:101 | SOX |
59900:102 | InterLAN-IX |
59900:103 | RoNIX |

Communities for peers with 32-bit ASNs:
Balkan-IX implements N:M filtering based on standard community strings. As standard BGP communities support only 4
bytes, this only works for 2-byte ASNs and peers with 2-byte ASNs.
Therefore, the following community format is applicable: <65000 + last octet from peer IP address>.
For BGP peers with 32-bit ASN use current table for community:
Peer | 32-bit ASN | BGP Community |
Rax.BG | 199364 | 65021 |
Delta.BG | 197216 | 65056 |
Mitko.Com | 199230 | 65061 |
