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.'.

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_route map_rule_add'.The syntax is: az network vhub route-map rule add --resource-group
                                   --route-map-name
                                   --vhub-name
                                   [--actions]
                                   [--match-criteria]
                                   [--name]
                                   [--next-step {continue, terminate, unknown}]
                                   [--no-wait {0, 1, f, false, n, no, t, true, y, yes}]
                                   [--rule-index]. The 1th example of the child command would be to use it to 'add rule to route map', the syntax is: az network vhub route-map rule add --name rule-name -g rg --route-map-name routemap-name --vhub-name vhub-name --match-criteria "[{matchCondition:Contains,routePrefix:[10.0.0.1/8]}]" --actions "[{type:Add,parameters:[{asPath:[22335]}]}]" --next-step Continue. The parameter '--resource-group -g' is required. It is used to name of resource group. you can configure the default group using `az configure --defaults group=<name>`.. The parameter '--route-map-name' is required. It is used to the name of the routemap.. The parameter '--vhub-name' is required. It is used to the name of the virtualhub containing the routemap.. The parameter '--actions' is optional. list of actions which will be applied on a match.  support shorthand-syntax, json-file and yaml-file. try "??" to show more.. The parameter '--match-criteria' is optional. list of matching criterion which will be applied to traffic.  support shorthand-syntax, json-file and yaml-file. try "??" to show more.. The parameter '--name' is optional. the unique name for the rule.. The parameter '--next-step' is optional. next step after rule is evaluated. current supported behaviors are 'continue'(to next rule) and 'terminate'.. The parameter '--no-wait' is optional. do not wait for the long-running operation to finish.. The parameter '--rule-index' is optional. the index of the route map rule..
