Abstract
The invention includes a method and apparatus for synchronizing line card forwarding databases. A method includes receiving a data packet at a line card, generating a control packet for each of at least one other line card to enable an address update operation thereat, and propagating the at least one control packet toward the at least one other line card. The control packet, or packets, is generated in response to a determination to perform an address update operation for the received data packet. The address update process may be implemented as an ingress address update process or an egress address update process. This address update process performed in conjunction with an address aging process.
