<div><br></div><div>Without the l3 agent, the 'isolated' mode can be enabled for the metadata access service. This is achieved by setting the flag enable_isolated_metadata_proxy to True in the dhcp_agent configuration file. When the isolated proxy is enabled, the dhcp agent will send an additional static route to each VM. This static route will have the dhcp agent as next hop and <a href="http://169.254.0.0/16" target="_blank">169.254.0.0/16</a> as destination CIDR; the dhcp agent will spawn a metadata proxy for each network. Once the packet reaches the proxy, the procedure works as above. This should also explain why the metadata agent does not depend on the l3 agent.</div>
<div><br></div><div>If you are deploying the l3 agent, but do not want to deploy the metadata agent on the same host, the 'metadata access network' can be considered. This option is enabled by setting enable_metadata_network on the dhcp agent configuration file. When enabled, quantum networks whose cidr is included in <a href="http://169.254.0.0/16" target="_blank">169.254.0.0/16</a> will be regarded as 'metadata networks', and will spawn a metadata proxy. The user can then connect such network to any logical router through the quantum API; thus granting metadata access to all the networks connected to such router.</div>
<div><br></div><div>I think the documentation for quantum metadata has not yet been merged in the admin guide.</div><div>I hope this clarifies the matter a little... although this thread has gone a little bit off-topic.
