It took all afternoon to install the icehouse. When establishing a network, an error is prompted:

The nova-network.log prompt for checking the compute node is as follows

Pay attention to the last line, which is out of range?

"is a general expression:

In order to distinguish the network, the subnet mask is generated: 0255256 is expressed in binary as 11111111 and 8 1s in total.

The subnet is also divided into four segments, that is, 255.255.255.2551111111111111111111111111111111321s.

Category C 255.255.255.011 1111111111111111111111111100000000001

Category B 255.255.0.01 11111111.11111111.00000000.000000001

Category A 255.0.0.01111111.00000000.00000000.000000008 1

There is also a common method for writing switch policies: inverting masks.

255.255.255.0mm 0.0.0.255

255.255.0.000.255.255

255.255.255.0mm 0.255.255.255 "
