Which two statements about wide and narrow metrics used in IS-IS are correct? (Choose two)
The correct answer is A. Wide metrics are sent by default and use 24 bits in TLVs to send information C. Disabling narrow metrics results in external routes being leaked from L1 to L2 areas automatically. With these TLVs, IS-IS metrics can have values up to 16,777,215 (224 - 1). By default, Junos OS supports the sending and receiving of wide metrics.
