I have set up a dhcpv6 client and server on an srx240 connected to a Comcast modem via ge-3/0/0.
I have enabled ipv6 flow mode and allowed dhcpv6 in the security zone.
ge-3/0/0 {
unit 0 {
description "untrust ethernet";
family inet6 {
dhcpv6-client {
client-type statefull;
client-ia-type ia-pd;
client-ia-type ia-na;
client-identifier duid-type duid-ll;
update-server;
}
}
}
}
dhcp-local-server {
dhcpv6 {
overrides {
interface-client-limit 10;
}
group IPV6 {
interface vlan.0;
}
}
}
address-assignment {
pool IPV6 {
family inet6 {
prefix 2601:248:4500:d3dc::/64;
range IPV6-RANGE {
low 2601:248:4500:d3dc::100/128;
high 2601:248:4500:d3dc::109/128;
}
dhcp-attributes {
propagate-settings ge-3/0/0.0;
}
}
}
}
I get a prefix delegation from Comcast.

I am pretty new at this and not sure how to proceed to get the dhcpv6 server working. Any help would be greatly appreciated.
Thanks.
