ABSTRACT:
A standalone router is integrated into a multi-chassis router. Integrating the standalone router into a multi-chassis router requires replacing switch cards in the standalone router with multi-chassis switch cards. The multi-chassis switch cards forward packets to a central switch card chassis for routing within the multi-chassis router. By incrementally replacing standalone switch cards with multi-chassis switch cards in the standalone router, packet forwarding performance is maintained during the integration.
