Hello.

I have 1 IP, and I want to reserve it on two servers. I want to have main
server and backup server.

Hi Anton,<br>
<br>
[...]<br>
<span class="">&gt; As I think, on the first server I discard any announce from \
second server<br> &gt; and conversely. But on both servers I see both servers as \
neighbors. Where<br> &gt; I&#39;m wrong?<br>
<br>
</span>You seem to have confused routes and OSPF adjacencies. You filter out<br>
routes imported from/exported into the OSPF area. That&#39;s possible but<br>
is only relevant for the local machine. Any route residing in the OSPF<br>
area will reach all routers (and maybe filtered out there).<br>
<br>
What you can&#39;t control with import/export filters is wether two OSPF<br>
routers are forming an adjacency so they become neighbors.<br>
<span class=""><br>
&gt; And maybe you suggest me another way for reservation ip on two servers?<br>
<br>
</span>I&#39;m not sure what you ment. Can you explain?<br>
<br>
Best<br>
