When the Routing Engine is removed, the SCB enters a warm shutdown mode and
continues forwarding data for a limited time using a frozen forwarding table. (The default

the warm shutdown period, the SCB unfreezes its forwarding tables and resumes normal
functioning. Otherwise, the SCB shuts itself down after the time limit expires.
