Which two logical router components span across all transport nodes?

TIER0_DISTRIBUTED_ROUTER: The Tier-0 Distributed Router spans all transport nodes, providing distributed routing capabilities across the NSX environment at the Tier-0 level.

DISTRIBUTED_ROUTER_TIER1: Similarly, the Tier-1 Distributed Router spans all transport nodes, enabling distributed routing at the Tier-1 level, which allows routing functions to occur closer to the workload VMs across the transport nodes.
