Open Stack

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
