M4300-12X12F keeps enabling IPv6 routing on reboot
Using 12.0.7.17 (latest) firmware on an M4300 switch. Everytime the switch is rebooted, it tries to become the default IPv6 router in my work network. I've tried to tell it no, and to save the config...
Hi unquietwiki
Welcome to Community!
I didn't face the problem on M4300-12X12F with image v12.0.7.17. It's work fine even when enable/disable IPv6 routing.
For further analysis,Could you please provide the tech-support file of the Switch:
How do I send tech-support files from my Managed Switch to NETGEAR community moderators?

Hi unquietwiki
Thanks for your immediately response, I received your switch tech-support file. And with your configuration, I can reproduce this problem your facing.
I notice there is IPv6 related configuration in your switch, and these two configuration will require enable IPv6 global. So this is the reason that switch will re-enable IPv6 Unicast Routing when reboot. And this is working as design.
'serviceport ipv6 address dhcp
serviceport ipv6 address autoconfig
interface vlan 1
routing
ip address 192.168.120.20 255.255.255.0
ipv6 address fdb9:17a4:71fd:11::7377:3032/64
ipv6 enable
ipv6 address autoconfig
exit'
Hope it helps!

Retired_Memberit sounds like my only fix here is to turn off IPv6 as a client on the switch, to avoid it becoming a router? I don't have this kind of issue with the newer 52-port switch we have; so I hope to be clear on what action to take here. Thanks.
