Aug 13, 2019
- Cisco Nexus 9000 Series Switches
Known Affected Releases
Symptom: Under certain conditions there may be duplicate PIM stripe winners causing inconsistencies in the behavior of ACI Pim Border Leafs. You would see "yes" in this output if you are hitting the issue: vsh -c "show fabric multicast globals" Atleast one dom del pending: yes If you see "no" then the BL is not affected. Conditions: The trigger is a combination of successive changes in PIM settings from regular convergence to fast convergence and back and then disabling of multicast on the VRF before the MRIB entries are removed.
