There is a command group 'az_network_vhub_connection'. This group of commands could 'manage virtual hub vnet connections'. The group of commands has global parameter '--debug' which means 'Increase logging verbosity to show all debug logs.'. The group of commands has global parameter '--help -h' which means 'Show this help message and exit.'. The group of commands has global parameter '--only-show-errors' which means 'Only show errors, suppressing warnings.'. The group of commands has global parameter '--output -o' which means 'Output format.'. The group of commands has global parameter '--query' which means 'JMESPath query string. See <a href="http://jmespath.org/">http://jmespath.org/</a> for more information and examples.'. The group of commands has global parameter '--subscription' which means 'Name or ID of subscription. You can configure the default subscription using `az account set -s NAME_OR_ID`.'. The group of commands has global parameter '--verbose' which means 'Increase logging verbosity. Use --debug for full debug logs.'. This group contains a child command 'az_network_vhub_connection_create'.The syntax is: az network vhub connection create --name

The 1th example of the child command would be to use it to 'create a virtual hub vnet connection without routing configuration', the syntax is: az network vhub connection create -n MyConnection --vhub-name MyHub -g MyRG --remote-vnet MyVNet. The 2th example of the child command would be to use it to 'create a virtual hub vnet connection with routing configuration', the syntax is: az network vhub connection create -n MyConnection --vhub-name MyHub -g MyRG --remote-vnet MyVNet --associated-route-table /subscriptions/MySub/resourceGroups/MyRG/providers/Microsoft.Network/virtualHubs/MyHub/hubRouteTables/RouteTable1 --propagated-route-tables /subscriptions/MySub/resourceGroups/MyRG/providers/Microsoft.Network/virtualHubs/MyHub/hubRouteTables/RouteTable1 /subscriptions/MySub/resourceGroups/MyRG/providers/Microsoft.Network/virtualHubs/MyHub/hubRouteTables/RouteTable2 --labels label1 label2 --route-name route1 --next-hop 70.0.0.2 --address-prefixes 10.80.0.0/16 10.90.0.0/16.
