DHCPv6 on Juniper SRX-110 - Progress

Last year I posted about my frustrations with getting the DHCPv6 client working on a Juniper SRX-110. I am pleased to report that Juniper has now released 12.1X46-D10.2, which resolves at least some of my issues. I couldn’t find it documented in the Release Notes anywhere, but the parser now allows you to have client-ia-type ia-pd without also requiring client-ia-type ia-na

It might not seem like much, but this is real progress for me - now my router can successfully reboot, without needing either a console cable, or resetting to a rescue configuration.

I haven’t yet had a chance to try getting the SRX to pass DHCPv6 prefixes from an external DHCPv6-client interface to the DHCPv6 server operating on an internal interface. In theory it should work, but I haven’t seen a complete working config. I don’t have an urgent need to fix that, as I have it working with RAs.
