Before you can begin using Magic Transit, be sure to complete the onboarding steps below. Cloudflare can significantly accelerate this timeline during active-attack scenarios.
1. Scope your configuration
The onboarding process begins with an initial kickoff call where Cloudflare engages with your organization to confirm the scope and timeline for setting up Magic Transit.
2. Configure tunnels
3. Run pre-flight checks
After Cloudflare stages the tunnels, Cloudflare validates tunnel connectivity, Letter of Authorization (LOA), Internet Routing Registry (IRR), and maximum segment size (MSS) configurations.
4. Advertise prefixes
Once Cloudflare’s pre-flight checks have passed and your account team verifies the date to complete the change, the process of onboarding your prefixes to Cloudflare’s edge network begins.
To configure the edge network, Cloudflare routes traffic sourced from Cloudflare’s network and attracts traffic from the broader Internet by advertising your customer-owned prefixes.
You control the edge router advertisement, which dictates whether Cloudflare’s edge network advertises your prefixes. Advertisement is activated at the go-live call, routing traffic via Cloudflare and the tunnels to your data centers.
If you are using a Cloudflare IP, you do not need to advertise your prefixes.
Duration: ~5 business days
5. Go live and announce prefixes
Once edge network configuration is complete, schedule a go-live call. During this call, you announce your prefixes from Cloudflare’s edge network for the first time.
