Abstract
A first network device receives a control message at an interface from a second network device, wherein the first network device and the second network device use a multipoint service that provides layer two (L2) connectivity between L2 networks. The control message specifies one or more L2 addresses of customer network devices that are provided connectivity to an autonomous system by the second network device, wherein the control message identifies the L2 addresses as static L2 addresses that are to be persistently maintained at the first network device as reachable by the interface. In response to receiving the control message and by the first network device, the first network device stores the L2 addresses as persistently maintained static L2 addresses being reachable by the interface at which the control message was received.
