Specify IP addresses for endpoint health checks
Magic Transit uses endpoint health checks to determine the overall health of your inter-network connections. Probes originate from Cloudflare infrastructure, outside customer network namespaces, and target IP addresses deep within your network, beyond the tunnel-terminating border router. These “long distance” probes are purely diagnostic.
When choosing which endpoint IP addresses to monitor with health checks, use these guidelines:
- Provide 1 IP address for each of the prefixes to be advertised by Cloudflare.
- Redundant IPs routed via the same ISP and infrastructure are not necessary but are useful when troubleshooting.
For an example endpoint health check configuration, refer to this table:
|Prefix||Endpoint IP address|
