Abstract
In one embodiment, a method according to the present disclosure includes receiving a topology change message at a core edge node and performing a network address information removal operation. The core edge node participates in network communications with one or more access network nodes of an access network using an access network protocol. The topology change message indicates that a topology change has occurred in the access network, and the topology change message conforms to the access network protocol. The network address information removal operation removes network address information stored by the core edge node, and the network address information is used by the core edge node in participating in the network communications.
