This is not a problem:

origin:       AS45328
descr:        Compendium, Buenos Aires, AR
country:      AR
prefix:       3FFE:8260::/28

*THIS* is a problem:


Border2-BGP> sh ipv6 bgp 3ffe:8260:2010:1:2a0:c9ff:fe01:9600

Come on, if Nicolas can get an ASN, so can COMPENDIUM.


Beyond that, if you peer with someone who uses a private ASN, use the
following command (or equiv for your router) on the peering session:

 neighbor 3ffe:xxxx::xxxx remove-private-AS

If your router code doesn't support that command or one like it, might I
suggest that you UPGRADE?
