t: Re: Community for small IX - problem with 4B ASN
Hello
I'm using some dirty trick for this
(It's example for some peer. Configs is generating automatically, so
template is the same for all peers, changes only currentas variable)
filter Peer_export
int currentas;
int myas;
I will use some private 16-bit ASn as before. For filters in our local IXP
should be ok.
Best wishes,
Piotr Marciniak

Well, that depends on exact meaning of 'communities'. There are three
different independent community attributes:
- 'traditional' communities (RFC 1997)
- Extended co

Please - do not explain me theoretical difference between 16 and 32 bits.
Question is simple - can I use 4B communities for filters? If not - what 16bit
"fake ASn" I can use instead safely?

1. Is it possible to enable 4B ASn for communities in Bird? Will it work
with other rouers?
2. Can we use instead private ASn just for community filters? Are they
processed corretly by other Internet routers of our peers?
1. Yes.

Hi Piotr,
I should use extended community for 4B ASN, because normal community is too
small “Encodes a 32-bit value displayed as “16-bit ASN:16-bit value”.

Or maybe there is another work around?

Dear Peter,
I strongly recommend to use a framework that generates your routeserver
configuration. By leveraging an existing framework you pull in important
features like prefix filtering and you leverage the work that others have
done before you.
I've had good success with arouteserver:

Hello,
We are running a small IX for around 20 members. A few months ago we moved on
Bird and actually I am trying to add some standard communities to prepend or
stop annoucing own prefixes to other members but can’t find examples on Bird
docs nor by Google. All I found looks limited only to ad
