CentOS 7 ens3.lease Error: 'classless-static-routes' Expecting Numeric Value

This error message indicates an issue with the network interface configuration file on CentOS 7. Specifically, there's a problem with the 'classless-static-routes' option on line 11 of the 'ens3.lease' file. The error suggests that the value for this option isn't a numeric value, which is what the system expects. To resolve this, edit the configuration file and ensure the 'classless-static-routes' option has a valid numeric value. After making changes, save the file and restart the network service to apply them. This should fix the error and enable the network interface to function correctly.
