OAM 介面和靜態路由

如果要使用 OAM 介面來部署閘道，請完成下列步驟。

新增額外介面給虛擬機器 (ETH2)。

VMware：如果需要用於管理/OAM 的專用 VNIC，請再新增一個 vmxnet3 類型的 vNIC。您必須重複先前的步驟，即按一下確定 (OK)，然後再次移至編輯設定 (Edit Settings)，以便記下 vNIC MAC 位址。

KVM：如果需要用於管理/OAM 的專用 VNIC，請確定您有名為 oam-network 的 libvirt 網路。然後，將下列幾行新增至 XML 虛擬機器結構：

…..
</controller>
<interface type='network'>
  <source network='public_interface'/>
  <vlan><tag id='#public_vlan#'/></vlan>
  <alias name='hostdev1'/>
  <address type='pci' domain='0x0000' bus='0x00' slot='0x11' function='0x0'/>
</interface>
<interface type='network'>
  <source network='inside_interface'/>
  <alias name='hostdev2'/>
  <address type='pci' domain='0x0000' bus='0x00' slot='0x12' function='0x0'/>
</interface>
<interface type='network'> 
  <source network='oam_interface'/>
  <vlan><tag id='#oam_vlan#'/></vlan>
  <alias name='hostdev2'/>
  <address type='pci' domain='0x0000' bus='0x00' slot='0x13' function='0x0'/>
</interface>
<serial type='pty'>
  <source path='/dev/pts/3'/>
  <target port='0'/>
  <alias name='serial0'/>
</serial>

在 network-config 檔案中設定其他介面。
