AS4665 is ours. We are ISI/LAP,3ffe:800::/24.
Sorry for poor aggregation. I will make filter for pTLA and sTLA.

But , our CISCO router looks something strange.

All bgp routes have permanent expire time.
So, any bogus BGP routes have never exipred.
I don't understand whether our configuration is something wrong
or IOSv6 have a bug.
Does anyone have same experiences ?

The contact person for AS4556 IPv6 network is me.
I apologize for our 6bone registry data is too old.
