Disclosed herein are system, method, and computer program product aspects for implementing anycast gateways. Some aspects of this disclosure relate to a method including receiving, by an access node, a first TLV from a first gateway. The first TLV includes a CMAC address for the first gateway, an IP address of the first gateway, and an L2 I-SID associated with the first gateway. The method further includes receiving, by the access node, a second TLV from a second gateway, where the second TLV includes the CMAC address, the IP address, and the L2 I-SID. The method further includes, in response to determining that the L2 I-SID exists in an LSDB of the access node, determining that the first gateway is closer to the access node than the second gateway. The method also includes storing the CMAC address in a database to point to the first gateway based on the determination.

Disclosed herein are system, method, and computer program product aspects for implementing a security group policy. Some aspects of this disclosure relate to a method for applying a security group policy. The method includes receiving a first frame from a source device and assigning a source security group identifier (ID) to the first frame. The method further includes generating a second frame based on the first frame and the source security group ID and identifying a target security group ID for the second frame. The method also includes applying one or more forwarding decisions to the second frame based on the source security group ID and the target security group ID.
