I joined an XR into an existing ISIS IGP.
Just Plain level-2 ISIS configurations only.
I can see information in "show isis database"
but not installed in routing table.
Any comments?

Hi,
Can you post the isis config and the output of both routing table and isis database?

any idea?
By the way, the adjacent router is a Nexus 7710 device.
Only ISIS LSPs coming from 7710 is not being installed in the ASR9K RiB.
I tested to enable ISIS with another adjacent router but this time another ASR9K and works fine.
Is there an issue with Nexus LSP propagation?

did you find solution to this, I have same scenario in reverses. I have ISIS configured between ASR9k and Nexus 9k and routes are not being installed in Nexus device but i can see those in ISIS database.

Unable to continue troubleshooting due the project was stopped.
Not sure if there's compatibility issues between XR and NX-OS.
12-12-2016 11:41 PM
apparently it was a bug and nxos was upgraded to resolve this.
12-13-2016 12:12 AM
can you share the bugID?
12-15-2016 12:21 AM
it was communicated as "internal" bug, so not pasted on cisco's website.
12-18-2016 08:02 PM
what NX-OS version solved the issue?
12-19-2016 09:30 PM
7.0(3)I2(2d) solved it.
