V5 co-exist with V4

We have a network of over 20 mt routers running ospf. If we load v5rc7 on one router will it peacefully co-exist with the others?

Thanks

Yes. It still implements the same protocols, barring any bugs - there might be some given that it’s an RC. I wouldn’t run RCs in production, but if you do, it SHOULD coexist fine.

rc7 has the same OSPF code as 4.16
