Cannot remove a self-IP when an unrelated static ARP entry exists. The system produces an error similar to the following: err mcpd[6743]: 01071907:3: Cannot delete IP <addr> because it would leave a static neighbor (ARP/NDP) entry unreachable.
Must delete static ARP entries in order to delete Self IP addresses.
Static arp entry exists, and there are no Self IP addresses on the same subnet as the static ARP entry. When in this condition, none of the Self IP addresses can be deleted.
None.
In this release, you can delete Self IP addresses if unrelated static ARP entries exist.
