Juno has introduced two new Neutron, routing related features: High availability of virtual routers, and distributed routing.

L3 HA is not compatible with L2pop and DVR.

DVR is not compatible with L3 HA and VLANs, but requires tunneling, L2pop and compute node external network connectivity.

Confused? So am I!

Here’s where we are now:

V – Compatible, X – Incompatible

And here’s what the community hopes to achieve for the next couple of releases:

• Integrate L3 HA with L2pop
• Integrate L3 HA with DVR
• Integrate DVR with VLANs

V – Compatible, X – Incompatible
