<p class="MsoNormal">Orange Cameroon is currently in the project of deploying IPV6 in the mobile network for the userplane. As we have two redundant core networks we have done the activation phase for one and we are currently testing. The testing is not successful
as service is experiencing high latency and is sporadic (works sometimes and other times it does not work). We will like your advice on this.<o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">New implementation of IPV6 in our mobile network. We are in the testing phase which so far is proving unsuccessful. We have configured the interfaces, routing in OSPF/BGP of IP Pools plus NAT64 for DNS resolutions. Sometimes during a browsing
test no security flow sessions detectable on firewalls When browsing succeeds the latency is very high such that service quality is very bad. We will appreciate a troubleshooting session to see if all is OK at the level of Juniper switch and firewalls. We
will appreciate a troubleshooting session so you can advice on what can be done in this case<o:p></o:p></p>
