Is there a way to create multiple external networks from Neutron's point
of view, where both of those networks are accessed through the same host
NIC? Obviously those networks would be using different subnets. I need
this sort of thing because the two subnets are treated differently by the

I am told that dual stacking is supported for compute instances. What
does that look like? Can I associate both an IPv4 and an IPv6 address
with a Neutron Port?
Thanks,

I am a little lost here, I have seen conflicting claims about where the
handshake ends. Are *both* sides receiving the SSH2_MSG_KEXINIT ? Can
you take packet traces anywhere in between your two endpoints?
I have seen networks include security middleboxes that are a little
incompetent --- when
I see https://wiki.openstack.org/wiki/NEUTRON-IPV6-MANUAL explicitly
disclaims interest in single-stacking and in Juno. Where would I go to
learn how to use IPv6 in the single-stack Juno case?
Thanks,
Mike

Is there any condition under which a Neutron router will route packets
from a provider network to a tenant network with destination address
unmolested? E.g., non-RFC1918 addresses on the tenant network? Does
Neutron know anything about RFC6598?
Thanks,
Mike

Indeed, I have exercised exactly this.

Is there a way to attach a routing rule to a network or subnet, with the
consequence that each device attached to that net or subnet gets that
routing rule?

I assume `--host-route` works with a destination that is a single host. Is
there something I can do to establish a routing rule for a destination
that is a CIDR block?

If my external network has multiple subnets, I think I have heard there is
a way to request a floating IP to be allocated on a specific one of those
subnets. How would I do that? CLI, API, and/or Python SDK. Liberty.
Thanks,

is to not forward
traffic to the RFC 1918 addresses. I do not recall how the Neutron
routers handle packets addressed to those addresses from sources on the
"outside".

BTW, when using packet tracing I find it troublesome to do the filtering
and/or the pretty-printing online; I simply capture all the packets at a
given interface and them examine them later with Wireshark.
