BGP communities with OpenBGPD

[Ludovic Collomb]

Hi,

I use OpenBSD (3.8) / OpenBDGP and it works fine whith 3 ISP.

I want to set outbound communutie to influence incoming traffic on 1 peer.

Here is the end of my bgpd.conf :

---------------------------------
[...]
neighbor aaa.bbb.ccc.ddd {
        remote-as       efg
        descr           My-ISP
        local-address   aaa.bbb.ccc.dde
        holdtime        30
        holdtime min    3
        announce        self
        set localpref   200
# I try to set community efg:xy42 ...
        set community efg:xy42
        tcp md5sig password xxxxxxxxxx
}

# filter out prefixes longer than 24 or shorter than 8 bits
deny from any
allow from any prefixlen 8 - 24

# do not accept a default route
deny from any prefix 0.0.0.0/0

# filter bogus networks
deny from any prefix 10.0.0.0/8 prefixlen >= 8
deny from any prefix 172.16.0.0/12 prefixlen >= 12
deny from any prefix 192.168.0.0/16 prefixlen >= 16
deny from any prefix 169.254.0.0/16 prefixlen >= 16
deny from any prefix 192.0.2.0/24 prefixlen >= 24
deny from any prefix 224.0.0.0/4 prefixlen >= 4
deny from any prefix 240.0.0.0/4 prefixlen >= 4

# and try to apply the filter attribute ...
match to aaa.bbb.ccc.ddd set community efg:xy42

---------------------------------

But My-ISP doesn't receive community efg:xy42 .

Where is the mistake ?

I was not able to find doc or samples on BGP communities with OpenBGPD.
Is there somebody have the same problem ?

Thank you in advance.
