This can be confirmed by turning on debugging of PPP negotiation: debug ppp negotiation If when the connection is being established, you see this: Vi2 IPV6CP: I CONFREQ [UNKNOWN] id 0 len 14 Vi2 IPV6CP: (0x010A020397FFFE168000) Vi2 LCP: O PROTREJ [Open] id 4 len 20 protocol IPV6CP (0x01000010010A020397FFFE168000) Vi2 PPP: Outbound ipv6 packet dropped, NCP not negotiated Vi2 PPP: Outbound ipv6 packet dropped, NCP not negotiated Then you will need to change to a version of IOS with the "advanced IP services" feature set. It looks like the basic IOS feature set does not support [https://tools.ietf.org/html/rfc2472 IPV6CP]. == TCP window scaling Bug == [[Category:~~IPv6]]~~3rd Party ~~[[Category:~~Routers\|Cisco]] [[Category:~~Router]] [[Category:ADSL~~IPv6]]
