When working with destination environments with Cross-vCenter NSX configurations, HCX supports extending source networks to destination environments using a Universal Distributed Logical Router (UDLR). When a UDLR is selected during the network extension operation, HCX creates a Universal Logical Switch on the destination across multiple vCenter Servers.
The following information and requirements apply for Network Extension when specifying a UDLR as the gateway.
The HCX Cloud Manager configuration includes all secondary NSX systems that exist in Configuration > NSX Manager at time of installation.
Secondary NSX systems must have the administrative credentials of its associated vCenter Server.
HCX Network Extension does not support the local egress feature of UDLRs.
