how to configure external network ethernet on compute node : nova networking
Sorry if it is very basic question. I was following basic environment setup on a centos 7 compute node and it says to configure the external network without an IP. How can ping http://openstack.org , work as suggested on the verification section if an IP is not set for the external network ?
I'm following the juno install guide for openstack
The external interface uses a special configuration without an IP address assigned to it. Configure the second interface as the external interface:
Replace INTERFACE_NAME with the actual interface name. For example, eth1 or ens224.
Edit the /etc/sysconfig/network-scripts/ifcfg-INTERFACE_NAME file to contain the following:
Do not change the HWADDR and UUID keys.
DEVICE=INTERFACE_NAME
TYPE=Ethernet
ONBOOT="yes"
BOOTPROTO="none"`
