    Default ISIS Comparison With OSPF

    ISIS level 1 -> similar to intra area in OSPF
    ISIS circuit level 1 and level 2-> similar to border router in OSPF
    ISIS DIS -> similar to DR in OSPF

    What is ISIS level 2 similar in OSPF? Anyone got a similar analogy?

    Level 2 is like the backbone
    Level 1-2 is the ABR
    Level 1 is any area other than the backbone connected to an ABR.

    Quick edit above, level 2 is like the backbone, it will receive the L1 LSPs from the L1L2 router. You should try and learn about the LSPs rather than looking at routes.
