|
|
Hi,
i'm trying to get ipv6 working with my gentoo xen vps. This is my /etc/conf.d/net

But a ping6 says:

ping6 2a00:f48:1026::1 is working.
ip -6 route says:

When i add
Quote: | ip -6 route add default via 2a00:0f48:1026::1; ip -6 route add 2a00:0f48:1026::1 dev eth0
|
it's working. So how can i get this without the command working in my net config?
I need to do this static, as the provider is not using RA or DHCPv6
thanks |

That won't help since the Hoster doesn't use Router Advertisement or DHCPv6. |

For now i use this:
Quote: |
postup() {
ip -6 route add 2a00:0f48:1026::1 dev eth0
ip -6 route add default via 2a00:0f48:1026::1
return 0
}
|
But is there no better way? |

Why /128, smallest should be /64.
Your System simply does not know Howto reach your Gateway, thats why your manual host route direct on the interface works. |

I received only the 16 IPv6 addresses.
I just thought setting the route stuff could be "easier" but it looks like the postup() seems to be the correct way for now. |

Why did you only Receive this few Addresses...
Code: |
routes_eth0="default via 62.113.200.1
2a00:0f48:1026::1 dev eth0
default via 2a00:f48:1026::1"
|
should do |

Your addresses are all set to /128, therefore they can only see a subnet consisting of themselves and nothing else. |

/128 - subnet for one IP-address |
