Hi,
I have some routing problems when I configure a server with ipv6 and dummy0
interface under Ubuntu server. With this network configuration:
iface dummy0 inet6 static
address fdab:cdef:abcd:1::2345
netmask 48
It creates a new route through dummy0 instead of a real network interface
(eth0/eth1). The kernel table looks like this:
fdab:cdef:abcd:1::/48 :: U 256 0
0 dummy0
fdab:cdef:abcd:1::/48 :: U 256 0
6 eth1
And I cannot ping any ipv6 address and I cannot use with the lvs server.
But, when I restart the dummy interface, the routing order change, so I got:
fdab:cdef:abcd:1::/48 :: U 256 0
6 eth1
fdab:cdef:abcd:1::/48 :: U 256 0
0 dummy0
and I can ping any ipv6 address and access the lvs server.
I don't have any problem with ipv4 and works nice with the lvs server. The
only difference is that the ip is under a dummy alias like this:
auto dummy0:0
iface dummy0:0 inet static
address 10.2.3.4
netmask 255.255.255.255
broadcast 10.2.3.4
Does anyone set up a server with this kind of ipv6 network configuration?
Is there a way to load the dummy interface at boot time without messing the
ipv6 routing table and restart the interface for fix it?
Regards,
