Content: The IAB-MT shall: 1> for each iab-IP-AddressIndex value included in the iab-IP-AddressToAddModList that is not part of the current IAB-MT configuration: 2> add the IP address indicated in iab-IP-Address, corresponding to the iab-IP-AddressIndex. 2> if added IP address is iPv4-Address: 3> if iab-IP-Usage is set to f1-C: 4> store the received IPv4 address for F1-C traffic together with the IAB-donor-DU BAP address corresponding to the iab-IP-AddressIndex. 3> else if iab-IP-Usage is set to f1-U: 4> store the received IPv4 address for F1-U traffic together with the IAB-donor-DU BAP address corresponding to the iab-IP-AddressIndex. 3> else if iab-IP-Usage is set to non-F1: 4> store the received IPv4 address for non-F1 traffic together with the IAB-donor-DU BAP address corresponding to the iab-IP-AddressIndex. 3> else: 4> store the received IPv4 address for all traffic together with the IAB-donor-DU BAP address corresponding to the iab-IP-AddressIndex. 2> else if iPv6-Address is included: 3> if iab-IP-Usage is set to f1-C: 4> store the received IPv6 address for F1-C traffic together with the IAB-donor-DU BAP address corresponding to the iab-IP-AddressIndex. 3> else if iab-IP-Usage is set to f1-U: 4> store the received IPv6 address for F1-U traffic together with the IAB-donor-DU BAP address corresponding to the iab-IP-AddressIndex. 3> else if iab-IP-Usage is set to non-F1: 4> store the received IPv6 address for non-F1 traffic together with the IAB-donor-DU BAP address corresponding to the iab-IP-AddressIndex. 3> else: 4> store the received IPv6 address for all traffic together with the IAB-donor-DU BAP address corresponding to the iab-IP-AddressIndex. 2> else if iPv6-Prefix is included in iab-IP-AddressToAddModList: 3> if iab-IP-Usage is set to f1-C: 4> store the received IPv6 address prefix for F1-C traffic together with the IAB-donor-DU BAP address corresponding to the iab-IP-AddressIndex. 3> else if iab-IP-Usage is set to f1-U: 4> store the received IPv6 address prefix for F1-U traffic together with the IAB-donor-DU BAP address corresponding to the iab-IP-AddressIndex. 3> else if iab-IP-Usage is set to non-F1: 4> store the received IPv6 address prefix for non-F1 traffic together with the IAB-donor-DU BAP address corresponding to the iab-IP-AddressIndex. 3> else: 4> store the received IPv6 address prefix for all traffic together with the IAB-donor-DU BAP address corresponding to the iab-IP-AddressIndex. 1> for each iab-IP-AddressIndex value included in the iab-IP-AddressToAddModList that is part of the current IAB-MT configuration: 2> modify the IP address configuration(s) in accordance with the IAB-IP-AddressConfiguration corresponding to the iab-IP-AddressIndex.
