General Discussion / Multi WAN and ipv6
« on: September 11, 2018, 07:17:41 am »
Hi
I have 2 WAN uplinks (cable and vdsl). IPv4 does work as expected and cable ipv6 to... but I have problems with forwarding the IPv6 prefix on the VDSL uplink...
thats are my settings:
cable interface (german vodafone cable)
vdsl interface (german 1&1 vdsl)
my first lan (should use cable for ipv6)
my second lan (should use vdsl for ipv6)
cat /var/etc/radvd.conf
here I'm missing something, there is no prefix on igb2... why?
cat /var/etc/dhcp6c_opt2.conf
cat /var/etc/dhcp6c_opt3.conf
There are 2 running dhcpd6c processes... it is normal?
in /var/log/dhcpd.log | grep dhcp6c I see this:
what can be the problem? what I'm doing wrong?

here I'm missing something, there is no prefix on igb2... why?

interface igb0_vlan4 {
send ia-pd 0; # request prefix delegation
request domain-name-servers;

};
id-assoc pd 0 {
prefix-interface igb1 {
sla-id 0;
sla-len 1;
};
};
cat /var/etc/dhcp6c_opt3.conf
Code: [Select]
interface igb0_vlan14 {
send ia-na 0; # request stateful address
send ia-pd 0; # request prefix delegation
request domain-name-servers;
request domain-name;
script "/var/etc/dhcp6c_opt3_script.sh"; # we'd like some nameservers please
};
id-assoc na 0 { };
id-assoc pd 0 {
prefix-interface igb2 {
sla-id 1;
sla-len 4;
};
};
There are 2 running dhcpd6c processes... it is normal?
in /var/log/dhcpd.log | grep dhcp6c I see this:

what can be the problem? what I'm doing wrong?
