IPv6 configuration
Getting IPv6 working on your router is actually easier than IPv4. This is because babeld doesn't require you specify an address on the interface which it will use as the next-hop address when redistributing routes from itself to neighbouring routers. Okay, that's a bit of a lie, it does require them but when you have IPv6 enabled an interface on Linux it automatically gets an IPv6 link-loal address which will be used as the next-hop address. You still however will want to add an IPv6 address to any one of your interfaces though so it can accept packets destined to it, this can be done however on any interface.
Step 1
Enable IPv6 on the interfaces you intend to run babeld on. I have no idea how to do this, but by default it is enabled, atleast on Raspbian.

Step 2
As with the previous tutorial on peering all you need to do is to have an interface line declared in your /etc/babeld.conf, nothing really changes just because you are doing IPv6. You will need to make sure you redistribute the following, so add this to your configuration:
# Redistribute all CRXN (IPv6 - fd8a:6111:3b1a::/48)
redistribute ip fd8a:6111:3b1a::/48 ge 48
