  1.4.01. IOS-XR structure Process-Level Redundancy Process-level redundancy is implemented by a system manager process creating the standby process. Because the active process created the standby process, the active process has all the information that it needs to communicate with the standby process. The active process uses a checkpoint database to share running state with the standby process. Symbolic links and abstract names are used to identify the processes. Clients do not see the standby process until the active goes away. If a process fails and it has created a standby process, a system-level process called QNet Symlink Manager (QSM) and a library called Event Connection Manager (ECM) are used to re-establish links from the clients to the processes.

  QSM provides:

  Distribution of symbolic link information

  Abstract name for a process or service

  ECM provides:

  Common information for connecting processes and services Detection of broken connections Only processes considered essential by development engineers are designated to support process- level redundancy. This is not a user-

  configurable option. Clients have to reconnect to the "new" active process (the "original" standby process) when they detect that the active process has failed. Clients can connect to it using the symbolic links and abstract names. The new

  active process creates a new standby process.

  The general steps in process redundancy are:

  The active process dies.

  The standby process becomes the active process.

  A new standby process starts.

  The new active process begins sending updates to the new standby process. Clients begin using the new active process through the symbolic links and abstract names.

• Question 324:

  Which two statements about EIGRP are true? (Choose two)

  C. Passive routes are in the process of being calculated by DUAL.
  D. EIGRP exchanges full routing table information with neighboring routers with every update.
  E. A query process is used to discover a replacement for a failed route if a feasible successor is not identified from the current routing information.
  A. EIGRP supports VLSM, route summarization, and routing update authentication.
  E. A query process is used to discover a replacement for a failed route if a feasible successor is not identified from the current routing information.
