Restore IPv6 Gateway Script Help.

[muffintastic]

Hello.

I've been having issues with my ISP (YouFibre) UK and their shoddy IPv6 (They won't admit it) (https://www.ispreview.co.uk/index.p...-2-56-million-uk-premises.html#comment-326015). I've now managed to fix this myself by using the command:

route -A inet6 add default gw fe80::aa7:41ff:feff:480c eth0

It seems their RA is all messed right now and RT-BE86U fails to acknowledge it but picks everything else up in regards IPv6 just not the gateway, don't worry this isn't a Merlin/Router issue. It is a Native based IPv6

How do I go about making this surviving a reboot or manually disconnecting my WAN or restore access if my WAN goes down. I would just like a script to auto do it. If someone could help me that would be great.

I have no idea whether this will work because I don't have IPv6. But my guess would be that you'd need a wan-event script something like this:

#!/bin/sh

if [ "$1" = "0" ] && [ "$2" = "connected" ]; then
    logger -t "$(basename $0)" "Adding route"
    route -A inet6 add default gw fe80::aa7:41ff:feff:480c eth0
