Add all peering VLANs to the bogon list by default

[Cybertinus]

No peering VLAN of no IX in the world should ever be announced in the DFZ. All the known peering VLANs can be found on PeeringDB, so that information should be used to add all the peering VLANs to the bogon list, so we will never accept such an announcement, should it reach our routers.

You mean "Peering LAN Prefix" instead of "VLAN"?

I'd argue that it depends from IXP to IXP whether the peering lan prefix should or should not be in the DFZ. What NTT does is reject peering lan prefixes from IXPs it is directly connected to; if this for whatever reason is not what the IXP wants there at least is a direct contractual relation to resolve the issue.

Blocking all peering lan prefixes listed in peeringdb seems over reaching
