Hi All, The above new draft has been posted to address an operational problem that exists with current IPoE (non-PPPoE) fixed line broadband services. It can be found here: https://datatracker.ietf.org/doc/draft-patterson-intarea-ipoe-health/
Hopefully the draft covers the problem statement sufficiently, but in summary, PPPoE makes use of LCP echo/replies to detect WAN failures, DHCPv4/6 currently has no such mechanism. After backhaul migrations or BNG maintenance/failure, an IPoE client can be left with a stale DHCP lease for up to the Valid Lifetime. This draft proposes the use of regular ARP and ND for link monitoring, to proactively expire DHCP leases early, and to trigger renewals or getting a new lease from scratch. The intarea WG was chosen as it doesn't neatly fit within the charters of either v6ops or dhc, and because it proposes new DHCPv4 and DHCPv6 Options. Although we expect discussions in both of these WGs as well. Thanks for comments already received from Ian, and Bernie, that helped shape this -00. -Richard _______________________________________________ Int-area mailing list Int-area@ietf.org https://www.ietf.org/mailman/listinfo/int-area
