I have been looking at the DHCPv6 server in JUNOS 15.1X49-D160.2. It is easy enough to setup Note: Step 5 is wrong, the first two instructions should have dhcpv6 as the last argument e.g.
set security zones security-zone untrust interfaces ge-0/0/0.0 host-inbound-traffic system-services dhcpv6
It would be nice to configure the DNS Search List option. The option code for this is 24. So I tried this
set access address-assignment pool my-pool family inet6 dhcp-attributes option 24 array string [ "sinodun.com" "ipv4.sinodun.com" ]
but it didn’t work. There appears to be no examples of how to do this correctly so after reading RFC3315 section 8 and RFC1035 section 3.1 I realised it had to be in uncompressed wire format like this
set access address-assignment pool my-pool family inet6 dhcp-attributes option 24 array hex-string [ "0773696e6f64756e03636f6d00" "04697076340773696e6f64756e03636f6d00" ]
which IMHO is not the easiest way to configure things.
