I checked on 2 PC with win 7 and problem the same.

Can anyone help with work configuration for end hosts and CPE the same time.

PS. I was trying this configuration on router 2851 with latest IOS. The problem was the same.

Re: Best practice of deployment IPv6 over PPPoE

IPv6 default router address comes from the RA. Please check

show ipv6 int Virtual-Template10

on the NAS and

netsh interface ipv6>show route

on the client.

In addition, you can debug RA messages.

Maybe some other useful info on my blog (though PPPoE is not covered):

In any case I have only default route.

In first case it doesn't work.

We found work combination for host clients and cpe (asus RT-N10U)

interface Virtual-Template10

ip unnumbered Loopback100

ip mtu 1492

no peer default ip address

peer default ipv6 pool 3PoE

ipv6 unnumbered Loopback1000

ipv6 enable

ipv6 mtu 1492

ipv6 nd ns-interval 1000

ipv6 nd other-config-flag

ipv6 dhcp server 3PoE rapid-commit

ppp authentication pap chap dialup_ppp

ppp authorization dialup_ppp

ppp accounting dialup_ppp

ipv6 dhcp pool 3PoE

prefix-delegation pool PD lifetime 120 120

address prefix 2A00:5CC0:BC36::/48

dns-server 2A00:5CC0:DC1::DC1

dns-server 2A00:5CC0:DC2::DC2
