Public bug reported: This looks like aftermath of fixing https://bugs.launchpad.net/neutron/+bug/1928466
According to docs https://docs.openstack.org/api- ref/network/v2/?expanded=create-port-detail#create-port the ip_address in allowed_address_pairs of a port can be a CIDR. Change https://review.opendev.org/q/I5d6c72c271ff450d9e43b3e33a99dd59d727882d (backported down to Queens) started calling _update_arp_entry method with ip_address of allowed_address_pairs. But when CIDR is supplied as such ip_address value, it now fails because CIDR can't be set on the device as a neighbor. TBH I am not clear what to do here. Should we unpack the CIDR and add arp entry for every IP in the range defined? Or should we ignore CIDRs altogether when adding arp entries? Or should we explicitly fail and deny allowed_address_pairs ip_address as CIDR in DVR? Or at all? ** Affects: neutron Importance: Undecided Status: New -- You received this bug notification because you are a member of Yahoo!
