This command creates a virtual network instance in ExtremeXOS. The virtual network instance maps to a bridge instance within ExtremeXOS.
| vn_name | Alphanumeric string identifying the Virtual Network to be created. |
| flooding | Configure flooding method for unknown-destination frames. |
| standard | Standard L2 flooding behavior to remote endpoints and tenant ports. |
| explicit-remotes | Explicitly configured flooding to remote endpoints with standard L2 flooding to tenant ports. |
| multicast | Multicast flooding to remote endpoints with standard L2 flooding to tenant ports. |
| group | Configure multicast group for flooding of unknown-destination frames. |
| grpipaddress | IPv4 multicast group address to be used for flooding (Automatically assigned if unspecified). |
Standard.
For auto-assigning multicast groups, you must configure the following command: configure virtual-network multicast group.
This bridge instance is not dependent on the overlay encapsulation scheme. The virtual network name can be a maximum of 32 characters. The current restrictions on naming objects in ExtremeXOS apply. Virtual network names are added to a new namespace within ExtremeXOS. Virtual networks may use one of two flooding methods for flooding to remote endpoints. The “standard” mode offers handling of unknown destination frames very similar to standard Layer 2. The unknown destination frames are flooded to all local ports and remote endpoints. The “explicit-remotes” mode offers granular control of which remote endpoints receive certain types of unknown destination frames. Different remote endpoint sets may be configured for; broadcast, unknown unicast, and unknown multicast. These sets are configured with create fdb and configure fdb commands
The following example creates the virtual network "my_virtual_network":
create virtual-network my_virtual_network
The following example deletes the virtual network "my_virtual_network":
delete virtual-network my_virtual_network
This command was first available in ExtremeXOS 21.1.
Multicast flooding support was made available in ExtremeXOS 31.2.
This command is available on all Universal switches and stacks supported in this document.
