With this feature, HeNB-GW supports IPv6 addressing on the core network, and dual-stack IP addressing on the access side when HeNB-GW is integrated with a Security Gateway (SecGW). An IPv6 address can be used in the crypto template associated with the HeNB-GW access service, and in the bind address of the HeNB-GW access service. Different or similar crypto templates can be configured with both IPv4 and IPv6 addresses, and associated with the same HeNB-GW service.
IPsec tunnels can be initialized, authenticated and established between HeNB and HeNB-GW using IPSec IKEv2 protocols over IPv6.
The configuration parameter IE in the IKE_Auth message directs the type of internal IP address allocated for the IPSec tunnel. The HeNB-GW access service can be configured to allocate a single or dual IP address, when a dual IP address is requested in the IKEv2 Auth request. When configured to allocate a single IP address, priority is given to IPv6. If the IPv6 address pool is not available or exhausted, then address from IPv4 pool will be allocated if available. When configured to allocate dual IP addresses, the SecGW will allocate both IPv4 and IPv6 address when available.
Use the bind s1-mme command to bind the pre-configured HeNB-GW Access Service to the IP address of the S1-MME interface.
Use the associate command to associate a pre-configured HeNB-GW network service and SCTP parameter template to the HeNB-GW access service.
Use the security-gateway bind command to configure the IPv4 and IPv6 address to be used as the connection point for establishing IKEv2 sessions, and to specify the crypto template to use for the security gateway (SecGW) for the HeNB-GW access service.
Use the security-gateway ip alloc-mode command to assign a single or dual-stack IP for the HeNB.
When ip alloc-mode is single and a HeNB requests for a dual IP, the HeNB-GW access service will try to allocate an IPv6 address to HeNB. If the IPv6 address is unavailable, an IPv4 address will be allocated. This is the default behaviour.
When ip alloc-mode is dual and a HeNB requests for a dual IP, the HeNB-GW access service will allocate both IPv6 and IPv4 addresses to HeNB based on availability.
Use the s1u-relay command to associate a pre-configured Access GTP-U service as well as the Network GTP-U service to this HeNB-GW Access Service for S1-U relay service functionality.
