32bit ASN peering with not AS4-capable peer

Sun Feb 02, 2014 6:05 pm

We have a public registered 32bit ASN from RIPE (say AS199999) and a public allocatet IPv6 prefix (say 2a01:ffff::/32). As our current upstream provider is only IPv4 capable but is in the process of deploying IPv6 we would like to test BGP with IPv6 over Hurricane Electric (AS6939). They are offering free 6to4 tunnels with the possibility to let me announce my own IPv6 prefixes. But unfortunately their router only supports 16bit ASN.
I managed to establish a BGP session with their router and got the whole IPv6 BGP table. But I'm unable to announce my own prefix. Don't know what I'm doing wrong.

Seems to be something with filtering. I disabled outgoing filtering and now my prefix is announced.
