Patent number: 11502872Abstract: Client device blocking may be provided. A switching device may receive data from a first client device. The data may be addressed to a second client device. Then it may be determined that both the first client device and the second client device belong to a protected group. Next, in response to determining that both the first client device and the second client device belong to the protected group, the data may be blocked from being forwarding to the second client device on a network interface of the switching device.Type: GrantFiled: September 22, 2021Date of Patent: November 15, 2022Assignee: Cisco Technology, Inc.Inventors: Atri Indiresan, Ramchander Rao Nadipally, Rahul Kachalia

Patent number: 11425044Abstract: This technology enables a dynamic host configuration protocol (“DHCP”) Layer 2 relay in a Virtual Extensible Local Area Network (“VXLAN”) overlay fabric. A host device broadcasts a configuration request, such as a DHCP discover, across an Ethernet virtual private network (“EVPN”) overlay fabric. The DHCP discover is intercepted by a VXLAN Tunnel End Point (“VTEP”) device with Layer 2 bridging functionality. The VTEP device selects a centralized gateway (“CGW”) device with Layer 3 relay functionality as a destination for the DHCP discover. The VTEP device encapsulates the DHCP discover with a unicast VXLAN header comprising the media access control (“MAC”) address of the CGW device and transmits the encapsulated DHCP discover to the CGW device, resolving the destination address associated with the broadcast. The CGW device transmits the DHCP discover to an Internet Protocol (“IP”) address associated with a DHCP server that is external to the EVPN overlay fabric.Type: GrantFiled: October 15, 2020Date of Patent: August 23, 2022Assignee: Cisco Technology, Inc.Inventors: Ramchander R. Nadipally, Ajinkya Abhay Chouthai, Rajagopal Venkatraman, Xiangqun Li, Rahul Kachalia
