Yes, you are right, that’s the problem, so , I also prefer to check the connected route, we should forbid the duplicated connected route, otherwise, connected route can’t recover. but in physical router, we could add the connected route with different priority, so I’m not sure whether the restriction is necessary. What do you think?

Maybe we need to check if the route is duplicated with the connected route before we add with API? Thanks.

I think we need to restrict the modification of connected route. I have reported a bug: https://bugs.launchpad.net/neutron/+bug/1339028 Any thoughts? Cheers, XuRong Yang
