Neutron Network Node High Availability

Sign up or log in to save this to your schedule and see who's attending!

Today, you can configure multiple network nodes to host DHCP and L3 agents. In the Icehouse release, load sharing is accomplished by scheduling virtual routers on L3 agents. However, if a network node or L3 agent goes down, all routers scheduled on that node will go down and connectivity will be lost. The Juno release will introduce L3 high availability as well as distributed routing.

L3 high availability schedules routers on more than a single network node. Stand-by routers use keepalive (And the VRRP protocol internally) to monitor the active router and pick up the slack in case of a failure. We'll explain what is VRRP and how will the feature affect the network node, as well as give a demonstration.

Distributed routing, or DVR, moves routing to the compute nodes, while keeping SNAT on the network nodes.

We'll talk about DHCP HA, go into a conceptual overview of both L3 HA and DVR, give demonstrations, and explain how to integrate them together to get the best of both worlds.
