Hi Sheng, I hope you're the right person for this, but if not, please let me know.
Currently I'm planning to work on the redundant routers in VPC (CLOUDSTACK-764) because my company will need this feature in the near future and you seem to have implemented the RvR in non-VPC networks. I think it is appropriate to follow the same implementation with yours, so can I get the review request information of this implementation so that I can reference your implementation if possible? Thanks. Alex Ough
