Usage: consul peering establish [options] -name <peer name> -peering-token <token>

Establish a peering connection. The name provided will be used locally by

this cluster to refer to the peering connection. The peering token can
|
|
only be used once to establish the connection.

|
|
Example:
|
|
|
|
$ consul peering establish -name west-dc -peering-token <token>
