The neutron l3 agent is responsible for providing service for routing, natting, security-group rules and floatingip allocation. This purpose of this post is to document its working principles and also to enable users to effectively debug their Openstack cloud(most problems occur due to user mis configuration). The l3 agent offers these services from the network node and relies on neutron-openvswitch-agent to provide l2 connectivity to the instances running on compute nodes. This post assumes that the readers are aware of how l2 connectivity is achieved using ‘openvswitch’ mechanism driver. Continue reading “L3 connectivity using neutron-l3-agent”
