First of all, we don't support this old version. Please upgrade, either to 1.6.4 or to 2.0.2.<br>
<br>
Second, the other side seems to send multiprotocol NLRI to you. BIRD in 1.x versions AFAIK does not support this extension and should not announce it. What is the remote software?<br>

Writing from my phone with no access to source code, trying to recall it from my memory. I might be wrong.<br>

Subject: BGP import route<br>

Hello,<br>
I'm not able to import route from BGP (CentOS 7). In log file I read "Got<br>
UPDATE" but "import updates" is always 0. With TCPDUMP I see that BGP<br>
receive the routes<br>
