ABSTRACT:
A device includes a primary control unit and a standby control unit. The standby control unit records routing communications exchanged between the primary control unit and an external routing device in accordance with a routing protocol. A standby routing process executing on the standby control unit processes the recorded routing communications when the primary control unit fails. The standby routing process generates state information for executing the routing protocol on the standby control unit without requiring that routing sessions be reestablished with the external routing device.
