Hi James,

 

Thanks first, but I encountered another problem when creating a VLAN interface according to the Red_Hat_Enterprise_Linux-7-Networking_Guide.  I configuered the parent interface ifcfg-eno1 as follows:

 

DEVICE=eno1

TYPE=Ethernet

BOOTPROTO=none

ONBOOT=yes

 

And I created a new file named ifcfg-eno1.1, the content is:

 

DEVICE=eno1.1

BOOTPROTO=none

ONBOOT=yes

IPADDR=192.168.81.66

PREFIX=24

NETWORK=192.168.81.66

VLAN=yes

 

Then I restarted the network: systemctl restart network (the operating system is CentOS7)

After that I found that I couldn’t connect to the Internet, even couldn’t ping the gateway. I thought it might be I didn’t set the GATEWAY in ifcfg-eno1.1, so I added the GATEWAY=192.168.81.254(My local area network gateway), it didn’t work. 

Could you teach me how to create a VLAN interface in CentOS7, or tell me what’ s wrong with my configuration, more detailed more better.

 

Thanks you

Hi Li,

 

Yes, this is absolutely possible. The easiest way would be to create a VLAN interface (e.g. eth0.50) for use as your management/API network as well as your VXLAN VTEP address, or you can create a separate interface for that. You will then use eth0 for your provider bridge interface (e.g. physical_interface_mappings = physnet1:eth0). You can then create a single flat and multiple VLAN provider networks using --provider:physical_network=physnet1 and segmentation IDs other than 50. The LinuxBridge agent will create VLAN interfaces and place them in the respective bridges.

 

James
