ifcfg [ DEVICE ] [ command ] ADDRESS [ PEER ]
This is a simplistic script replacing one option of ifconfig , namely, IP address management. It not only adds addresses, but also carries out Duplicate Address Detection RFC-DHCP, sends unsolicited ARP to update the caches of other hosts sharing the interface, adds some control routes and restarts Router Discovery when it is necessary.
- - it may have alias, suffix, separated by colon.
- - add, delete or stop.
- - optionally followed by prefix length.
- - optional peer address for pointpoint interfaces.
