Understanding Redundant SIBs
Purpose
Inspect redundant SIBs to ensure that they provide the switching function to the destination FPCs.
What Are Redundant SIBs
Redundant SIBs are multiple SIBs that are installed in the M320 router, T320 router, and the T640 routing node. In the event of a failure, one of the SIBs acts as backup for the failed SIB. For more information, see SIB Location and Redundancy.
Table 116 shows the SIB characteristics for the M320 router, T320 router, and the T640 routing node.
