[AusNOG] Juniper SRX300 on Aussie Broadband NBN HFC - DHCP Issue

[Tim Dykes]

Thanks everyone for the replies,

an industry contact has said that there is a known Juniper issue that is
only fixed in the latest junos v20 nightly. Issues only affect IPOE
delivered HFC services, PPOE HFC is fine.

Let's not even get started on the issues the nightly v20 has, but let's
just say it's not safe to run in production.
