Which of the following is a difference between IS-IS and OSPF?
IS-IS uses OSI addressing, which distinguishes it from OSPF. OSI addressing is unique to IS-IS, whereas OSPF uses IP addressing. This is a clear difference between the two protocols.
OSPF supports manual summarization. IS-IS uses OSI Network Layer Addressing, which is done through NSAP Addresses that identify any system in the OSI Network.
