I am using Mikrotik CCR for my core routes and network. For every CPE Router I am using the Cambium cnPilot 201 or 201p. However, I cannot guarantee ipv6 on my network with this hardware. I need the configuration to setup the router to automatically start serving IP addresses from the Ipv6 PD pool that was given to the router. I can manually setup the DHCPv6, but I cannot guarantee that the ipv6 prefix won't change the next time the router reboots and asks for a new prefix.
edit: the router should instead be acting as ICMPv6(stateless) for local machines. and is set in the ipv6 LAN page by default.
Any help would be appreciated.
On another issue, i cannot get any ipv6 connectivity through PPPoE, but i believe that to be a mikrotik issue.
edit: the pppoe issue will be fixed in next firmware release.
Thank you for quick reply. The pppoe issue is less portent issue. I have core router ( mikrotik ccr) running PPPoE server set to delegate /64 prefixes from a /49 pool authenticated through radius. The cnpilot is directly connected to ccr with ethernet cable and acquires a prefix through PPPoE however no ipv6 connectivity is made between cnpilot and ccr. When using dhcpv6 there is no issue of connectivity. Again, I believe this to be mikrotik issue not cambium.
My biggest issue is next, if the cnpilot does receive a prefix, it does nothing with that prefix. I go to the ipv6 Lan tab, but there is no option to set the cnpilot to dhcp the network addresses using the prefix that was dynamically assigned. I can only get addresses assigned when I put everything in manually. How should the ipv6 Lan tab be set up to utilize the prefix that was delegated to the cnpilot? Additionally, how do I make the cnpilot automatically assign itself an ip from the same pool? Or should that be done from the core router? I mean, I should not need more than a prefix delegation to allow the router to connect to the ccr?
Thanks, that has gotten me closer. My router is now giving out dynamic IPs from the delegated prefix. However end to end ipv6 connectivity is still an issue. The issue is that the cambium router seems to not add a default route to the internet(2000::/3) to go through the core router/wan interface.
I've added a couple screen shots detailing the issue.
The First screen shot is my computer conected to the cambium router. First, pinging the cambium router, no issue, pinging the core router, no issue. Then when i try to ping the wan interface of the core router, the cambium router says no route to host. If I attempt to ping netflix(or any website) then still, cambium router says no route to host. The second screen shot is me using a mikrotik hAP AC lite(a $40 router...) in the exact same configuration using PPPoE to obtain a prefix from the core router. You will notice instantly that end to end connectivity is apparent in pinging netflix.com. Next i did a traceroute to ipv6.google.com, showing that it first pings the mikrotik router, then the core router, then my provider's gateway(.....c002:1::1). This shows that my core router is correctly set up to delegate and route IPv6.
biggest issue i have with cnpilot is that the fd00 subnet is local site which means not global routed they need to fix it to allow dhcp-pd to the lan then all you need to do is set your prefix delegation to be always the same. which can be configured by radius or long lease time.
wan should be manually configured or automatically by EUI-64
Query has been answered on the previous post . Please find the attached doc for ipv6 prefix delegation to work on R-Series routers . This doc mentions a workaround for ipv6 + pd set up to get this working . This issue will be fixed in 4.6 (where you won't need a workaround)
