== Routing IPv6 over PPP == |
|||
If you are having trouble trying to get IPv6 to route over PPP, it might be because the version of IOS you are using doesn't support it. |
|||
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 |

|||
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]. |
