IPv6 over PPPoE routing

[cpw]

Hi
So, I have previously posted on this topic, and it still seems to be a problem even with latest 22.1.4. I have IPv6 available from my DSL provider (TekSavvy), via PPPoE. I can confirm I get an IPv6 address, and prefix delegated from them (via PPPoE IPv4 connection).

However, I never get any routes to the PPPoE connection for IPv6. These are the ONLY two routes related to pppoe0 in the entire route table.

Code: [Select]

ipv6 fe80::%pppoe0/64 link#17 U NaN 1492 pppoe0 DSL
ipv6 fe80::4262:31ff:fe06:af3c%pppoe0 link#17 UHS NaN 16384 lo0 Loopback

I have a multiwan setup, and the IPv6 routing on the cable connection works fine. I had a problem a few weeks ago with the cable connection however, and the cable connection was fully disabled, so my only connectivity for a couple of weeks was the DSL/PPPoE. This did NOT change anything about IPv6 routing for the PPPoE connection, so I was effectively off IPv6 for this period of time.

My speculation is that something about PPPoE is not updating the routing system when PPPoE fully provisions it's IPv6 route (which happens a short time after IPv4 comes up, because it has to wait for IPv4 connectivity to request the IPv6 information).

How would I go about trying to diagnose this problem?
