I have one public IP from my ISP 198.51.100.123/21 and a public 203.0.113.1/29 subnet routed by my ISP through the first IP.
OS: CentOS 7.
I want to assign each IP from the /29 subnet to a virtual NIC. How can I do that?
You may edit
/etc/sysconfig/network-scripts/ifcfg-e* (whatever it is named on your system) and add the additional IP addresses. For example:
IPADDR=198.51.100.123 PREFIX=21 IPADDR2=203.0.113.1 PREFIX2=29 IPADDR3=203.0.113.2 PREFIX3=29 IPADDR4=203.0.113.3 PREFIX4=29 IPADDR5=203.0.113.4 PREFIX5=29 IPADDR6=203.0.113.5 PREFIX6=29
