I am a little disappointed, I wanted to be officially proficient in it.

    Take CCNP SP or CCIE SP Path and you will see it there. You also run into a few tidbits of IS-IS under the CCIE DC track.
    CCIE Sec: Starting Nov 11

    IS-IS is an uncommon routing protocol to encounter unless you work for a Service Provider, until recently when the rise of layer 2 overlays have become more prominent in certain places. If you ever start working for someone running Fabricpath, SPBm/v, VXLAN, OTV, etc, you will definitely see it, more so being used as a L3 control plane for L2 forwarding intelligence.

    It's on the CCIE (R&S) Written Exam. IS-IS is not a common routing protocol in your average company.
    R&S: CCENT → CCNA → CCNP → CCIE [ ]
    Security: CCNA [ ]
    Virtualization: VCA-DCV [ ]
