Public bug reported: When using Neutron Segments we would like dhcp agent to configure DHCP servers to serve clients on remote(non-local) subnets. The remote(non- local) subnet will need to have a DHCP-relay/forwarder configured. The relay agent will run on ToR switch or router in the routed underlay network and would be configured by the operator, it does not need to be managed by neutron.
Currently the Neutron Segments implementation expect a DHCP agent to be available on all segments, and thus non-local subnets are filtered in dhcp_rpc to return only subnets local to the agent. To support DHCP relay we need to return all subnets and inform the DHCP agent wich subnets are local vs non-local so that the DHCP agent will only bind port/ip-address to the subnets that is local. Implementation of the dhpc_rpc part of this has been started with these reviews: https://review.openstack.org/#/c/459861/ https://review.openstack.org/#/c/438171/ https://review.openstack.org/#/c/462209 The discussion in comment 10 of this bug 1668145 is relevant: https://bugs.launchpad.net/neutron/+bug/1668145/comments/10 ** Affects: neutron Importance: Undecided Status: In Progress ** Tags: l3-ipam-dhcp ** Changed in: neutron Status: New => In Progress -- You received this bug notification because you are a member of Yahoo!
