Using ISC DHCP client 4.2.6 (dhclient -6 -P ....) /w SB6121 occasionally my /64 PD stops passing traffic. Manually forcing lease renewal restores traffic.
While this always happens when modem reboots it is also happening randomly while the modem is operating normally and has not lost sync.
Is there anything I am doing wrong or can change to fix this? Does Comcast do whatever the equivalent of lease query is for IPv6 or is there some other way routers are expected to handle this?
I ASSume something in Comcast land is losing state and can't restore itself without lease renewal.
