1. What is the problem?
The current implementation of bridge networks has some problems
when supporting DVR and shared VxLAN network. One blueprint has
been registered[1] and the specification document has also been
submitted[2].
2. What is the solution to the problem?
The logic of bridge network operations will be changed, here lists
some major changes:
(1) Only one bridge network will be created for one project
(2) Bridge network is attached to local router as external network
(3) One local router dedicated for north-south networking will be
created in the pod hosting real external network. Bridge network
is attached to this special router as internal network
(4) If the instance port is not located in the pod hosting real
external network, after floating ip association, one "copy" port
will be created in the pod hosting real external network. Without
this port, local Neutron server will complain that it cannot find
the internal port going to be associated.
3.What the features need to be implemented to the Tricircle
to realize the solution?
Bring part of the DVR support to cross-pod layer-3 networking
