Hello @fly
2023 Feb 15 09:12:34 N7K2 %ICMPV6-3-ND_LOG: icmpv6 [4130] Own mac address 0000
.0000.002e in the RS packet received on Ethernet2/8 from fe80::200:ff:fe00:2e
In this case, the switch is receiving an RS packet from a link-local address and the source MAC address in the packet is the same as the switch's own MAC address. This is likely due to the fact that the switch itself is sending the RS packet, possibly as part of the Neighbor Discovery process or as part of an IPv6 network configuration change.
This message itself is not an error or a cause for concern, but rather a notification that an RS packet was received by the switch with its own MAC address as the source
%OSPFV3-4-SOURCE_ERR: ospfv3-1 [24822] (default) Bad source address fe80:: - ours on port-channel101
Have you got the OSPFv3 instance configuration please ?
Best regards
