IPv6 DHCP Relay with PD not installing route

Mon Jan 23, 2017 3:45 pm

Hi

I try to use a Mikrotik CCR as a IPv6 Gateway for a bigger network. Client CPE gets its prefix via DHCP6 PD. The CCR has a DHCP6 Relay configured but does not install the prefix it hands out to the Customer CPE into the local routing table. When I configure the DHCP Server locally on the CCR the route gets added to the table.

What I am lokich for is that the relay behaves the same as the local server:
http://wiki.mikrotik.com/wiki/Manual:IP ... delegation
--> DHCP-PD also installs route to assigned prefix into IPv6 routing table

I have not found a config option to do so. Anyone has the same problem.

Regards

Matthias

Same problem here!

mikrotik install route on the server, where is DHCP-SERVER, but correct behavior is to install route there, where is DHCP-RELAY.

Adding the route for the relayed prefix is still not available in 6.44. Mikrotik, please fix! This makes IPv6 DHCP relay pretty useless without it.

I ended up enabling DHCP logging and writing a script to read the log and add the prefix that way. I have the script on a scheduler and running every minute. Quite a pain, but it was the only real automated way I could think of to do it.

Hi sawilkinson2,

Did you ever get this to work in a native way? I currently do it with a script/api call from our dhcp server. Not great, but works.

Will this feature (IPv6 DHCP Relay installing Prefix Route) perhaps be implemented in RouterOS 7?
