How to delete this IPv6 default route?

Installing and Using OpenWrt Network and Wireless Configuration

I'd like to delete the 2nd route listed here:

default from 2001:999:x:672::/64 dev 6in4-wan6  proto static  metric 1024  pref medium
default from 2001:999:y:671:: dev 6in4-wan6  proto static  metric 1024  pref medium
2001:999:x:672::/64 dev 6in4-wan6  proto kernel  metric 256  pref medium
fdc1:8e54:45::/64 dev br-lan  proto static  metric 1024  pref medium
unreachable fdc1:8e54:45::/48 dev lo  proto static  metric 2147483647  error -113 pref medium
fe80::/64 dev eth0  proto kernel  metric 256  pref medium
fe80::/64 dev 6in4-wan6  proto kernel  metric 256  pref medium
fe80::/64 dev br-lan  proto kernel  metric 256  pref medium

I've tried a bunch of different combinations of ip -6 route del and route -A inet6 del but I can't get rid of it...

It doesn't show up in route -n either

You [wisely] redacted the IPs; but in their entirety. You could have just removed the last 'hex-tets' that Identify the assigned subnet and machine.

Obviously, I do not see the string "0671"...so I cannot assist.

There's also other things off with the config that may hinder IPv6 Internet access on LAN; but I'm trying to stick to just the topic. I think you have another thread going for the setup of Tunnelbroker, perhaps you should consider sticking to one thread.

What's the problem with this route? It's only used with packets originating from one single address, 2001:999:y:671::, anyway.

I guess the following should delete it, but it probably will show up again if it wasn't added manually.
ip -6 route del default from 2001:999:y:671:: dev 6in4-wan6

Problem is only Tunnelbroker support told me to delete it. They are helping me troubleshoot it
