Characteristic of ISIS point-to-point link

what are Characteristic of ISIS point-to-point link  



  • 1. Same IIH PDU for L1 and L2;

    2. There is no DIS (thus no DIS election);

    3. Explicit acknowledgement of LSPs (CSNP are sent to adjacent IS. PSNP is sent back acknowledging LSP receipt. Note: there is no acknowledgment in broadcast links. The process is different, centered on DIS).

    This is what I can think of now...
