VxLAN ExtremeXOS Considerations

Consider the following items before configuring a VxLAN topology with ExtremeXOS switches:

• The physical interface that handles the ExtremeXOS local endpoint IP address must be different than the attached physical port for the Tenant VLAN for VxLAN VNI. You must have at least two trunk ports to separate local endpoint traffic and tenant VLAN traffic.
  Example:

  

  ​​configure vlan VLAN_3000 add ports 48 tagged​
  configure vlan VLAN_3000 ipaddress 10.47.1.104 255.255.254.0​
  configure virtual-network local-endpoint ipaddress 10.47.1.104 vr "VR-Default“​
  
  ​configure vlan VLAN_3105 add ports 47 tagged​
  configure virtual-network "IDAP" vxlan vni 8192​
  configure virtual-network "IDAP" add vlan VLAN_3105
  ​configure virtual-network IDAP add remote-endpoint vxlan ipaddress 10.47.100.100 vr VR-Default​
  configure virtual-network IDAP add remote-endpoint vxlan ipaddress 10.47.100.108 vr VR-Default​
  configure virtual-network IDAP add remote-endpoint vxlan ipaddress 10.47.100.109 vr VR-Default​

• A remote endpoint (AP) must be at least one hop away from the ExtremeXOS local endpoint.

  The configuration must include at least one gateway router between the AP and the switch. The gateway must enable IP MTU (Maximum Transmission Units) of 1550 bytes.

  Example:

  

  configure vlan VLAN_3000 add ports 48 tagged​
  configure vlan VLAN_3000 ipaddress 10.47.1.104 255.255.254.0​
  configure virtual-network local-endpoint ipaddress 10.47.1.104 vr "VR-Default“​
  
  ​configure vlan VLAN_3105 add ports 47 tagged​
  configure virtual-network "IDAP" vxlan vni 8192
  ​configure virtual-network "IDAP" add vlan VLAN_3105​
  configure virtual-network IDAP add remote-endpoint vxlan ipaddress 10.47.100.100 vr VR-Default​
  configure virtual-network IDAP add remote-endpoint vxlan ipaddress 10.47.100.108 vr VR-Default​
  configure virtual-network IDAP add remote-endpoint vxlan ipaddress 10.47.100.109 vr VR-Default​
