IPv6 Route Advertisement and DHCPv6 relay


#1

I am setting up IPv6 environment but I can not find out 2 things:

  1. I need to distribute DNS info in Router Advertisement ICMP messages.
    I know that Vyos uses RADVD for IPv6 RA configuration, so radvd.conf file in Linux looks like this

interface eth6
{
AdvSendAdvert on;
MinRtrAdvInterval 3;
MaxRtrAdvInterval 10;
AdvManagedFlag on;
AdvOtherConfigFlag on;

prefix fd00:172:16:5::/64
{
};

RDNSS fd00:172:16:5::4
{
AdvRDNSSLifetime 10;
};

DNSSL ipv6a.qual.lab
{
AdvDNSSLLifetime 10;
};
};

For example, in Brocade Vyatta implementation, I found following command to configure DNS

ipv6 nd ra-dns-server fd00:172:16:5::4

Is there way to specify both RDNSS and DNSSL in VyOS?

  1. I need to configure DHCP IPv6 relay on my VyOS router. Is it possible?
    Unbuntu for example has

dhcp6relay – DHCPv6 relay agent
http://manpages.ubuntu.com/manpages/precise/man8/dhcp6relay.8.html

Does DHCPv6 relay agent exist in VyOS?

Thanks
