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 as specified in Configuration > NSX. Each secondary NSX listed must have the administrative credentials of its associated vCenter Server.
HCX Network Extension does not support the local egress feature of UDLRs.
