Fixed In Version: NetworkManager-1.43.3-1.el9
Doc Type: Enhancement
Doc Text:
Feature: NetworkManager now offers the ability to configure the ns_ip6_target option for bond interfaces, allowing up to 16 IPv6 addresses to be specified as monitoring peers when arp_interval is set. Reason: Prior to this update, there was no support for specifying IPv6 monitoring peers for bond interfaces in NetworkManager. This enhancement was necessary to provide equal capabilities for IPv4 and IPv6 settings. Result: With this new feature, users can now configure the ns_ip6_target option in NetworkManager using the nmcli command. Once the new option is added to the bond.options, NetworkManager applies it to the bond interface effectively, thereby enabling the specification of IPv6 addresses as monitoring peers when arp_interval is set.

Description Hangbin Liu 2022-03-28 04:23:54 UTC 
Description of problem:

Please help add bond new option ns_ip6_target for NM. Here is the kernel doc[1]

ns_ip6_target

        Specifies the IPv6 addresses to use as IPv6 monitoring peers when
        arp_interval is > 0.  These are the targets of the NS request
        sent to determine the health of the link to the targets.
        Specify these values in ffff:ffff::ffff:ffff format.  Multiple IPv6
        addresses must be separated by a comma.  At least one IPv6
        address must be given for NS/NA monitoring to function.  The
        maximum number of targets that can be specified is 16.  The
        default value is no IPv6 addresses.


And kernel commit [2], iproute2 commit [3] for reference.

Oh thanks for reporting this. I didn't know ns_ip6_target could satisfy that condition too. Let me fix it, it is simple. Thanks!
Comment 12 Hangbin Liu 2023-04-24 06:43:48 UTC 
FYI, it works now:

# rpm -q NetworkManager
NetworkManager-1.43.6-1.el9.x86_64
# nmcli con add type bond ifname bond0 bond.options "mode=active-backup,arp_interval=200,arp_missed_max=15,ns_ip6_target=fe80::210:18ff:feaa:bbcc"
Connection 'bond-bond0' (37c4fae6-5255-4acc-9882-2bd16c77d4ab) successfully added.
# nmcli con show bond-bond0 | grep "bond.options"
bond.options:                           mode=active-backup,arp_interval=200,arp_missed_max=15,ns_ip6_target=fe80::210:18ff:feaa:bbcc

Thanks
