Abstract: The present disclosure provides systems, methods, and non-transitory computer-readable storage media for determining container to leaf switch connectivity information in a data center in a presence of blade switches and servers. In one aspect of the present disclosure, a method of determining container to leaf switch connectivity information of a data center utilizing at least one blade switch and at least one blade server, includes receiving, at a network controller, link connectivity information that includes south-bound neighboring information between the at least one blade switch of the data center and the at least one blade server of the data center; determining, at the network controller, the container to leaf switch connectivity information of the data center, based on the link connectivity information; and generating a visual representation of a topology of the data center based on the container to leaf switch connectivity information.

Abstract: In one implementation, a method performed by a first node with interfaces configured as IP unnumbered interfaces sharing a single IP address and to communicate with a DHCP-associated second node includes: obtaining a first message that indicates a configuration status of a third node at a respective interface; obtaining a second message for the third node from the DHCP-associated second node that includes a temporary IP address for the third node and an indicator of a file server; obtaining a third message associated with the third node that includes the temporary IP address, the third message requests address information for the file server; and configuring the third node by establishing a connection between the third node and the file server to transfer at least one configuration file, where configuring the third node includes providing the temporary IP address to the DHCP-associated second node via BGP.

Abstract: In an example, there is disclosed a network switch, including: an ingress interface; an egress interface; an endpoint repository network interface; and one or more logic elements including an endpoint admission control engine to: receive a packet on the ingress interface, the packet having an associated source Internet protocol (IP) address and virtual network identifier (VNI); query an endpoint repository via the endpoint repository network interface for the source IP address and VNI; determine that the source IP address and VNI are found in an endpoint repository database of the endpoint repository; and forward the packet to a destination IP address via the egress interface.
