<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt"> Does FRR OSPF support neighborship on an P2P interface with Multiple Interface IP addresses? I am using multiple 32bit host ip address on same interface.</span><o:p></o:p></p>

<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt"> When I try to establish ospf neighborship on an P2P interface with multiple IP addresses assigned, OSPF neighborship keeps resetting due to, receival of interleaving hello of 1<sup>st</sup>
or 2<sup>nd</sup> ip-address. Is there any way to avoid this and bring up sessions on the Interface.</span><o:p></o:p></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt"> </span><o:p></o:p></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt"> Above thing works good if the Interface IP addresses are assigned < 32 bit subnet mask (for example, 10.0.0.1/24 instead of 10.0.0.1/32).
