Abstract
In one embodiment, a method according to the present disclosure includes receiving a topology change advertisement at a remote core edge node and performing a network address information removal operation. The topology change advertisement is received from a core edge node that is in communication with an access network. The topology change advertisement indicates that a topology change has occurred in the access network. The network address information removal operation removes network address information stored by the remote core edge node. The network address information is used by the remote core edge node in participating in communications with the core edge node.
