Are you fine with adding a socket > option something like SHIM_INITIAL_PEER_LOCATOR in the multihome shim > API document (this one)? procedurally, I'm not really fine with this because then we have to change anyway the native HIP API. It is already referring to SHIM_LOC_PEER_PREF, SHIM_LOCLIST_PEER and SHIM_LOC_PEER_SEND: http://tools.ietf.org/html/draft-ietf-hip-native-api-12#section-4.6 Technically, I am not convinced if having a separate constant for initial locator is really needed. It seems that we have the following options: 1. Override the statement in the native HIP API draft 2. Remove the statement in the SHIM API 3. Cross-reference the native HIP API draft 4. Document the exception for HIP in the SHIM API I would be in favor of 2 and perhaps 3. What about others? > The socket option can be described as follows: > > - The socket option allows application to specify the destination IP > address to send HIP I1 message. > - This socket option is accepted only when the multihoming shim > sub-layer is HIP.
