3.11.5.2 Receiving Message #2

  • Article

When the host receives the CFG_REPLY (as specified in [RFC4306] section 3.15) for the INTERNAL_IP4_SERVER or INTERNAL_IP6_SERVER attribute, it MUST validate the message (as also specified in [RFC4306] section 3). Additionally, the host SHOULD:<32>

  • See whether the server has sent an internal IPv4 address or an internal IPv6 address.

  • If either or both are present, store these values in its local data structures and use these addresses to send packets to the internal address of IRAS.

Any failures in this exchange MUST NOT affect the state of the IKE_SA.
