OSPF Neighbor Relationship Is Down after module removal

[KDG_dhkd]

Hello, Everyone

There was a problem with the nexus chssis module, so OIR was performed.

While checking the progress of OIR, I checked that OSPFv3 went down and then went up.

If anyone has the same or similar problem as me, could you please tell me the solution?

PID : Nexus7018

OIR module : N7K-F248XT-25E

NX-OS version : 6.2(14)

hello,

Currently, there is talk that it may be a module type problem. (m1 or f2e)

and Since M1 is an EOS module, it is not possible to test in TAC, so we plan to test it internally.

If you want the test results, we will share them later.
