DEPRECATED - PLEASE USE NEW GRE INSTRUCTIONS

These instructions walk through configuring an Ubuntu 24 machine to reach other nodes via Regional Edge. These steps cover installing and configuring WireGuard and FRR. WireGuard is used to create a tunnel to the Regional Edge. FRR is used to add/remove routes via Regional Edge as remote nodes become available. If a remote node is not attached to the SCION Sui network,

Prerequisites

• Two IP addresses
  • Public IPv4 address by which this node is “known” across Sui.
  • Public IPv6 address to be used for the connection to the Regional Edge.
• Ubuntu 24
  • These steps have only been tested on Ubuntu 24.

Outline

These steps should be done

• Submit a Node Connection Request.
  • Submit a request to connect your node to a selected Regional Edge. This kicks off the process by having the Regional Edge operator configure the tunnel and routing on the remote (Regional Edge) side.
• Await confirmation Regional Edge Confirmation.
  • The Regional Edge operator will send a Notion notification (email) once they have processed your request. This will include providing the WireGuard Edge Public Key assigned for your tunnel.
• Configure the WireGuard connection on your node.
  • This will setup the tunnel from your node to the Regional Edge.
• Configure FRR on your node.
  • This will turn on routing over the WireGuard tunnel to the Regional Edge.
• Test and Debug.
  • Verify that routes are being accepted and test connections to a remote node.
• Performance Test.
  • Verify that routes have the proper latency characteristics.
