Abstract: The disclosure provides an approach for virtual computing instance (VCI) migration. Embodiments include scanning logical segments associated with a customer gateway to identify network addresses associated with the logical segments. Embodiments include determining one or more recommended supernets based on the network addresses associated with the logical segments. Embodiments include providing output to a user based on the one or more recommended supernets. Embodiments include based on the output, receiving input from the user configuring an aggregation supernet for the customer gateway. Embodiments include advertising the aggregation supernet to one or more endpoints separate from the customer gateway.

Abstract: Some embodiments provide a method for configuring a DCN migrated from a first host computer at a first site of multiple sites spanned by a logical network to a second host computer at a second site. At the second host, the method receives, from the first host, data for configuring the DCN and implementing the logical network on the second site. The data includes (i) data particular to the first site and (ii) a global identifier for a logical port to which the DCN attaches. The method provides the global identifier to a local logical network manager, which uses the global identifier to retrieve data regarding the logical port from a global network manager that manages the logical network across the sites. Based on data retrieved from the global network manager, the method modifies the data particular to the first site into data particular to the second site.
