Hello,
I setup IPv6 anycast (client) (RFC 3068) on my 1812 router. The router is using a pppoe dialer 1 via vlan 10 (FTTB-network that uses VLANs between vdsl-modem and IAD).
Here you go with the config:
--- cut ---

The thing is that everything just works just as expected. IPv6 RA (router solicitations) just appear after the tunnnel 64 is up and IPv6 internet can be used. After a while (I guess when the dialer needs to redial) this appears in the log:

Those entries are there everytime the dialer goes down and up again. The only way to gain connectivity back it by booting the router.
