Abstract: One embodiment provides a system which facilitates scaling of routing in an EVPN. During operation, the system determines, in an Ethernet Virtual Private Network (EVPN), a plurality of virtual tunnel endpoints (VTEPs) coupled to a plurality of subnets, wherein a respective subnet includes one or more hosts, wherein a first VTEP is configured with a first number of host routes for a first subnet coupled to a second VTEP, and wherein each of the first number of host routes corresponds to a host residing in the first subnet. Responsive to detecting that a total number of routes configured on the first VTEP exceeds a first predetermined threshold, the system aggregates the first number of host routes by replacing the first number of host routes with a first prefix route which indicates the first subnet.

Abstract: One embodiment provides a system and method for managing, at a network node, a data structure indicating neighbor node address information. During operation, the system can determine, based on a media access control (MAC) address or an Internet protocol (IP) address associated with an entry in the data structure, a type of the entry, and set a timeout value for the entry based on the determined type. In response to detecting that an entry corresponding to the MAC address expires in a MAC table maintained by the network node, the system can identify an interface on the network node to which a neighbor associated with the MAC address was previously coupled and transmit a unicast neighbor-probe packet on the identified interface to determine a connection status of the neighbor.
