=Config with Tunneled IPv6 Fallback=
If using AAISP, then the options for IPv6 routing on the [[:Category:Control Pages|Control Pages]] allow an IPv6 block to be routed to a tunnel endpoint if the main routing (ie ADSL/FTTC) goes down. This means IPv6 can be routed to the 3G dongle if the main broadband(s) go down. The MTU will be limited though.
==Example Config==
This assumes the 3G dongle has an MTU of 1500. When MTU is 1492, RA-MTU is 1472.
