IPv6 Autogeneration Not Persisting

Syed, Nabeel <nabsyed@...>

I’m trying to auto-generate IPv6 for interfaces on a ZPE Systems device but not able to. It keeps reverting to a value of ‘1’ after a reboot even though the config file clearly has ‘3’. Anyone run into something similar?



root@device:/home/admin# cat /proc/version

Linux version 5.4.137-yocto-standard (oe-user@oe-host) (gcc version 9.3.0 (GCC)) #1 SMP PREEMPT Sat Jul 31 06:19:39 UTC 2021


root@device:/home/admin# sysctl net.ipv6.conf.sfp0.addr_gen_mode

net.ipv6.conf.sfp0.addr_gen_mode = 1


root@device:/home/admin# cat /etc/sysctl.conf | grep net.ipv6.conf.sfp0.addr_gen_mode
