We have a CCR1036-8G-2S+ which we are having troubles configuring IPV6 on.
The problem appears that there is no default gateway outbound so we get ‘no route to host’ errors when we trace and traceroute out of our /48 block.
We have compared our config to another 8G-2S+ and note that this also doesn’t have a default ::0/ gateway set, but is able to auto discover the outbound path.
Our BGP session is up, and we can see the route table has loads of routes. I was thinking of adding in the local-link address as the default gateway, but as this is a production system we didn’t want to push this without checking this would be an appropriate measure.
Could anyone point me in the right direction? we are using ROS 6.5 firmware 3.09
I have the same problem.. i have implemented IPv6 in my 4 core routers.
Three of them are CISCO routers, and the other is mikrotik CCR.. i have /64 in the mikrotik CCR..
I inserted ::/0 default route to point to one of the CISCO.. but /64 users cant get routed to the core 3 routers.
Is it a bug??? i tested with five RB750 routers.. and configured default routes to each other.. but it didnt work//
I just had this issue as well. The Cisco router wasn’t showing up in the IPv6 neighbor list and ROS refused to send IPv6 forwarded packets the direction of any static route. Its as though ROS ignores ND packets from the cisco side if its sending RAs as well or the Cisco side doesn’t send NDs when its sending RAs. Maybe its a bug that ROS will only forward packets to a router listed with that attribute in the neighbor table.
I have not been able to fully test but one change that did fix the issue for me was the following setting.
/ipv6 settings set accept-router-advertisements=yes
the default is
/ipv6 settings set accept-router-advertisements=yes-if-forwarding-disabled
