Section: 6.2.11 Multi-homed IPv6 PDU session
Content: The UE supporting IPv6 may support multi-homed IPv6 PDU session. If the UE supports the multi-homed IPv6 PDU session: a) the UE shall support acting as a type C host as specified in IETF RFC 4191 [36]; and b) the UE indicates support of the multi-homed IPv6 PDU session: 1) during the UE-requested PDU session establishment of a PDU session of "IPv6" or "IPv4v6" PDU session type; and 2) during the UE-requested PDU session modification performed after an inter-system change from S1 mode to N1 mode, for a PDU session associated with a PDN connection established when in S1 mode, if the UE is a UE operating in single-registration mode in a network supporting N26 interface, the PDU session is of "IPv6" or "IPv4v6" PDU session type, and the UE has not previously successfully performed the UE-requested PDU session modification to provide this indication.
