1. What is the problem?
Multiple north-south external network topology is supported,
but the east-west networking for local networks across multiple
OpenStack clouds has not been supported yet.
2. What is the solution to the problem?
In multi-region cloud deployment, a requirement is that each
OpenStack cloud provides external network, north-south traffic
is expected to be handled locally for shortest path, and/or
use multiple external networks to help application north-south
traffic redundancy, at the same time east-west networking of
tenant's networks between OpenStack cloud is also needed.
This path will introduce east-west gateway router to address
the east-west networking for local networks in different
OpenStack clouds.
3. What the features need to be implemented to the Tricircle
to realize the solution?
East-west gateway router.
