Subject: [mobile-ip] key exchange between MN and MAP in HMIPv6

Hi,

I have a question about key exchange between MN and MAP in HMIPv6
(draft-ietf-mobileip-hmipv6-07.txt).

In Section 12.1, there is the following paragraph:

   The MAP needs to set the SA for the RCoA (not the LCoA). This can be 
   performed with IKE [6]. The mobile node  uses its LCoA as source 
   address but specifies that the RCoA should be used in the SA. This is 
   achieved by using the RCoA as the client identity in IKE Phase 2 
   negotiation (Quick mode).  

In my understanding, ISAKMP-SA must be established in IKE Phase 1
before IKE Phase 2 is executed. The draft does not mention ISAKMP-SA establishment. How is ISAKMP-SA established between MN and MAP in HMIPv6?

Best regards,
