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

[Christopher Hawker]

I’ve seen similar issues when replacing routers on ABB’s HFC services. The problem turned out the DHCP lease was tied to the MAC of the old router. A 2-minute call to Support saw the lease kicked and the new router able to retrieve an address. Not just for Juniper, any brand.

Searching around we have found references to a DHCP issue where the juniper sends DHCP options out of order (or that NBN fiddles with options in a way that only effects Juniper) but cannot find any definitive answer or anything saying this was true/false fixed or unrelated.
