By connecting to DoubleZero I agree to the DoubleZero Terms of Service

Detailed connection information:

Please follow the setup instructions to Install and configure the DoubleZero client.

2. Connection Instructions

Connect to DoubleZero in Multicast Mode As a publisher:

doublezero connect multicast --publish <feed name>

or as a subscriber:

doublezero connect multicast --subscribe <feed name>

or to publish and subscribe:

doublezero connect multicast --publish <feed name> --subscribe <feed name>

To publish or subscribe to multiple feeds you can include multiple feed names space separated. This can also be use to publish and subscribe to publish feeds. For example doublezero connect multicast --subscribe feed1 feed2 feed3

You should see output similar to the following: 

⚡  Connecting to devnet...
    DoubleZero ID: <your DoubleZero ID>
⚡  Provisioning for IP: <your public ip>
    Creating account for IP: <your public ip>
    Device selected: <the doublezero device you are connecting to>
✅  User Provisioned

3. Verify your active multicast connection.

Wait for 60 seconds and then run

doublezero status
Expected result: - BGP Session Up on the correct DoubleZero Network - If you are a publisher, your DoubleZero IP will be different than your Tunnel Src IP. This is expected. - If you are a subscriber only, doublezero status leaves DoubleZero IP blank. doublezero user list shows it.
