Configuring an IS-IS interface to automatically adjust the link cost based on link quality facilitates route selection control and improves network reliability.
A bit error refers to the deviation between a bit that is sent and the bit that is received. The bit error rate (BER) refers to the number of bit errors divided by the total number of bits transferred during a studied time interval. During data transmission, a high BER may degrade or even interrupt services.
To prevent this problem, configure IS-IS interfaces to automatically adjust link costs based on link quality so that unreliable links are not used by the optimal routes.
