A platform team uses WAN federation to connect three Consul datacenters: dc1, dc2, and dc3. Services in dc1 need to communicate with services in dc3 via the service mesh without a direct network path between dc1 and dc3. How can mesh gateways be used to enable this connectivity?

Question

Accepted Answer

B. Deploy mesh gateways in each datacenter; Consul routes dc1-to-dc3 traffic through dc2 as an intermediate hop via the mesh gateway chain. In a WAN-federated Consul deployment with mesh gateways, Consul can route service mesh traffic through intermediate datacenter mesh gateways when a direct path does not exist. A service in dc1 sends traffic to dc3 via dc1 mesh gateway, then dc2 mesh gateway, then dc3 mesh gateway, following the WAN federation topology. Option a is wrong because this chaining behavior is explicitly supported.
