invalid prefixes advertised

[Jan Oravec]

Hello,

I see a lot of invalid prefixes advertised in BGP table received from
several peers of XS26 network.

If I ignore non-aggregated prefixes received, the following invalid prefixes
are in global BGP:

2001:4b00::/35 0 8277 15589 11630 i
- not delegated

2001:a00::/35 0 8277 15589 1275 i
- according to IANA, not delegated
2002:a00::/35 0 8277 15589 1275 i
- same AS source - 1275 - configuration error? -> 6to4 of 10.0.0.0/19
2003::/16     0 8277 45328 278 237 5761 ?
