Usage: consul peering <subcommand> [options] [args]

  This command has subcommands for interacting with Cluster Peering 
  connections. Here are some simple examples, and more detailed
  examples are available in the subcommands or the documentation.

  Generate a peering token:

    $ consul peering generate-token -name west-dc

  Establish a peering connection:

    $ consul peering establish -name east-dc -peering-token <token>

  List all the local peering connections:

    $ consul peering list

  Print the status of a peering connection:

    $ consul peering read -name west-dc

  Delete and close a peering connection:

    $ consul peering delete -name west-dc

  For more examples, ask for subcommand help or view the documentation.
