Dear all,

TL;DR: Perhaps it is time to add 2002::/16 to our EBGP bogon filters?

It is kind of strange that in the default-free zone (where we donâ??t
announce defaults to each other) - we will propagate what is effectively an
IPv4 default-route, in the IPv6 DFZ.

IETF has politely abandoned the prefix:
https://tools.ietf.org/html/rfc7526

Wes George highlighted operational problems from accepting 2002::/16 on the
data-plane slide 6:
http://iepg.org/2018-03-18-ietf101/wes.pdf

Is there still really any legit reason left to accept, or propagate,
2002::/16 on EBGP sessions in the DFZ?

Kind regards,

Job
