Tplink (OEM firmware) with DHCP disabled, on LAN, as a simple AP : fe80 address creates issue with ipv6 of LAN

Installing and Using OpenWrt Network and Wireless Configuration

Hi,

I connected a classic tplink router, with OEM firmware, disabled it's DHCP, connected it on the lan port, to use it as a simple wifi AP.

it's connected to an openwrt router.
The thing is, I dont understand why, it creates a second ipv6 default route, on computers, such as :

default via fe80::aaaa:bbbb:cccc:dddd dev wlp2s0 proto ra metric 600 pref medium
default via fe80::1111:2222:3333:4444 dev wlp2s0 proto ra metric 600 pref medium

and slows downs ipv6 traffic to the openwrt. Is there a way to change this? I've never encountered this issue before. Looks like it's from the lan side of tplink router, with auto generated fe80 address.

Is there any option to disable router advertisement for IPv6 with the TP link firmware?

Since this device is using the vendor firmware, you need to ask them about this issue since it's not related to (and cannot be solved by) the OpenWrt upstream router.

What device is it? If it is supported, a good option would be to flash it over to OpenWrt.
