Public bug reported:
neutron-dynamic-routing is broken due to merging
https://review.opendev.org/#/c/665426/, which adds the argument
'agent_timestamp' to _log_heartbeat(). All neutron-dynamic-routing jobs
are failing with errors like these

I have a routed provider network with 2 segments. Prior to creating an
IPv6 subnet on a segment, I have created IPv4 subnets and attached a
router to the external network without issue. When I attempt to create
an IPv6 subnet on a segment, the following occurs:

Public bug reported:
Currently, neutron enforces that on any given network, all subnets of
the same address family (IPv4/6) must be all allocated from the same
subnet pool. This restriction was put in place before the concept of
address scopes existed, and was meant to help enforce the uniqueness

This involves the following items:

* Support for distributed SNAT

Public bug reported:
I've been noticing the scenario jobs in neutron-dynamic-routing (non-
voting) failing intermittently. Upon further investigation, it appears
these failures are happening when attempting to disassociate a
bgpspeaker from an agent.

I am observing StaleDataError on stable/pike during live migration,
causing live migration to fail. It occurs when attempting to live-
migrate a handful of VM's (5-6 VM's is all it takes) in rapid succession
from the same source to the same target. This quick and dirty script
Public bug reported:
The current implementation of neutron-dynamic-routing is compatible with
DVR, but is not optimized for DVR. It currently announces next-hops for
all tenant subnets through the central router on the network node.
Announcing next-hops via the FIP gateway on the compute node was
Public bug reported:
I was seeing a user pass an uppercase UUID from their app to the Nova
API's. Their calls failed with a 500 error and the following exception
in the nova-api log:
017-05-24 11:20:27.176 68631 ERROR nova.api.openstack

This is actually correct behavior. For a subnet to be advertised, we
require it to be allocated from a subnet pool that is in the same
address scope as the gateway network.

Public bug reported:
Enable BGP to announce the next-hop for fixed IP host route when using
DVR. The next-hop when using DVR is the IP address of the FIP agent
gateway. This would allow an operator to toggle whether to enable
announcement of host routes for each fixed IP or just rely on the prefix

Public bug reported:
In its current state, distributed north-south flows with DVR can only be
acheived when a floating IP is bound to a fixed IP. Without a floating
IP associated, the north-south flows are steered through the centralized
SNAT node, even if you are directly routing the tenant netwo
Public bug reported:
It is currently not possible to take an existing subnet and move it into
a subnetpool or address scope. The subnetpool_id attribute on subnets
is not updateable, meaning that once a subnet is created it cannot be
moved between subnetpools or address scopes. If a subnet was c

When using DVR, if traffic is sent to the fixed IP of an instance using
the FIP gateway as the next-hop it is dropped by the FIP gateway. The
FIP gateway should act as a generic gateway to both fixed IP's and
floating IP's. This is an enabler for north-south DVR without usin
