Folks: I have this Cisco 2901 configured with PPPoE and IPv6 and connect it through a CO (DSLAM) to an Actiontec xDSL router. PPPoE connections are on FE0/0/0, through virtual template.
The Actiontec router gets NA and PD addresses succesfully and LAN PC connected to Actiontec router can surf the IPv6 Internet w/ no problem. However, Cisco 2901 can't reach the Actiontec router by its NA or TA public IPv6 address. A 'stupid' workaround is to manually add a route w/ the virtual access. It is stupid cuz each new connection will bring up a different virtual acess.
I guess this is a bug on 2901, but want to confirm with you guys first. Now the whole config:

See both IPv4 and IPv6 are using virtual template to get PPPoE work. Everything's working fairly well on IPv4. I can ping from cisco to the 10.11.11.x address on Actiontec router. But with IPv6, I can't ping 2001:470:1f05:7a:: address on Actiontec router. The correct route through virtual-access is not installed, or the F0/0/0 interface doesn't pass the IPv6 traffic to the corresponding virtual access interface:

Can some help? Thanks!
