Cluster I/O Protocols (CIP) Configuration and Management Manual (H06.16+, J06.05+)

All the routes belonging to an interface for a particular network are automatically deleted from
the kernel when the last IPv4 address belonging to that network is deleted from the interface.
However, the routes remain in the configuration file. These routes will come into effect only
when the interface is restarted (ifstop followed by ifstart) or when the routes are deleted and
then added back after adding at least one IPv4 address corresponding to that network. For
example:
interface -info eth5
Interface : eth5
Interface Type : Physical Interface
MTU Size : 1500
IP Address : 172.17.190.71
Netmask : 255.255.255.0
ROUTE Details :
- Route Type : Default Route
Destination Address : 0.0.0.0
Netmask : 0.0.0.0
Gateway Address : 172.17.190.1
Metric : 0
Minimum RTO : Unspecified
When the IP 172.17.190.71 is deleted, the default route 172.17.190.1 is automatically
deleted from the kernel.
