<div>Hi Kien</div>
<div> </div>
<div>I read your mail from the mailing list, which u have replied for Rohit. It had the subject</div>
<div> <strong>[Dsmip] Need Help in IPv4 - IPv6 Handover Support"</strong></div>
<div> </div>
<div>I have applied the patches as mentioned by u in the mail, followed both README. But facing issues, when I switch from HL to ipv4 FL network. Mentioned all my details in previous two mails send to DSMIPv6 mailing lists, with subject as:</div>
<div> </div>
<div> <strong>[Dsmip] MR not able to send BU, when move from HL to FL(ipv4 n/w)</strong></div>
<div> </div>
<div>I want to know that whether we need some ipv4 routing advertisement daemon, when MR moves from HL to IPv4 only network. If yes, on what machines, do we need to run it. Please provide some pointer. So that I can proceed further.......</div>

<div><font color="#330000"><br></font><font color="#330000">When we move from HL to ipv4 FL, this is the flow of MIP code:</font></div>

<div><font color="#330000"></font> </div>
<div><font color="#330000">The last routine is returning NULL as there is no entry of default router in the list. And if it is NULL, then the routine <strong>mn_home_rtr_chk()</strong> is not called. And the flag (<strong>at_home</strong> in <strong>home_addr_info</strong> struct) is not set as 0. Flags previous value is 1, which means that we are in HL. So the routine <strong>mn_move()</strong> is not called. This is the reason movement detection is failing, when we move from HL to IPv4 network.</font></div>

<div><font color="#330000">In case, when we move from HL to IPv6 network, that time the routine <strong>md_add_default_router()</strong> is called, which add the entry for default router in list.

<div>Hi All</div>
<div> </div>
<div>I am new to this group and facing some issues, while moving MR from home link to foreign link(ipv4 network). The MR is not sending BU to HA. When seen in the mip6d logs, the movement detection code is not getting triggered. But when I start the mip6d daemon( in MR) in FL(ipv4 network), then MR sends the BU to HA. Attaching the mip6d logs for MR in both scenario. </div>
<div> </div>
<div>a. In the logs, we see the below error messages. </div>
<div> mip6d[4330]: Interface 7 (sit0):type 776 unsupported<br> mip6d[4330]: Interface 9 (tunl0):type 768 unsupported<br> mip6d[4330]: Interface 15 (sit1):type 776 unsupported<br>
mip6d[4330]: Interface 16 (tunl1):type 768 unsupported</div>
<div> </div>
<div> Do we need some specific patch to fix the above error message. Till now I have applied the following </div>
<div> patches.</div>
<div> 1. NEPL basic patch<br> 2. umip-dsmip-20080530.tar<br> 3. umip-dsmip-v4traffic-20081021.tar</div>
<div> </div>
<div> The linux kernel used is linux-2.6.24. Please provide some pointer to proceed further.</div>
