<p class="MsoNormal">I am trying to switch from Quagga to FRR,
but I am having issues adding distributed IPv6 routes.
Although the IPv6 routes get added, they keep toggling between
being added and removed. This did not occur while using
Quagga.

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">A difference between the added IPv6 routes
of Quagga and FRR was that (1) the Quagga routes are by
protocol zebra and (2) the FRR routes are by protocol 186,
which I deduced to be bgpd. This can be seen by initiating the
command “ip -6 ro sh”.<o:p></o:p></p>

<p>I think, the display of 186 it just because you need the
`friendly` names specifying</p>
<p>You could edit etc/iproute2/rt_protos and add the missing numbers
and the output would look better. See below.</p>
<p>I suspect this is not why routes are being added and withdrawn.<br>

<p>Not sure what else to say. Can you post some more config?</p>
<p>if you type <br>
<br>
do show ipv6 route <a prefix></p>
<p>what comes out?</p>
<p>Is the next hop accessible?</p>
<p><br>
</p>
<p>I'd keep trying, because FRR fixes so many IPv6 problems you
don't know were problems until you switched to FRR :)<br>
