Hi, shihanzhang. I still have a question about routed network. I have two subnets. One is 10.1.0.0/24 and the other is 10.1.1.0/24. I create two instances in each host. Such as 10.1.0.10 and 10.1.1.10.
My question is, how does 10.1.0.10 connect to 10.1.1.10 ? There is no any gateway( 10.1.0.1 and 10.1.1.1 ) in each subnet. Hope four your reply. ;-) Thanks Zhi Chang 2016-11-01 14:31 GMT+08:00 zhi <changzhi1...@gmail.com>: > Hi, shihanzhang. > > Thanks for your advice.
