Hello,

I'm using JUNOS Software Release [12.1X46-D65.4]. I have configured IPv6 SLAAC for a VLAN segment and don't see where I can add in the IPv6 DNS Servers either on the VLAN, the System, or the VLAN Interface. I'm getting stateless IPv6 addresses on the segment, just that no IPv6 DNS servers are showing from the end user computer. Which I can understand, until I have them configured somewhere? The only place I can seem to enter IPv6 DNS servers is under the "System" configuration, but once I do that, my IPv4 DNS stops working and I still never see the IPv6 DNS on the user end. Can someone please point me as to where I can enter this data? A small snippet of my configuration below:

protocols {
router-advertisement {
interface vlan.7 {
prefix 2001:438:2d:10::/64;

unit 7 {
family inet {
address 10.10.10.1/24;
}
family inet6 {
address 2001:438:2d:10::1/64;
system {
}
name-server {
208.67.220.220;
208.67.222.222;
}
name-resolution {
no-resolve-on-input;

Hi,

You can read below KB

https://kb.juniper.net/InfoCenter/index?page=content&id=KB25760

IPv6 DNS can be provided using DHCPv6.

Router Advertisement will have M and O flag.

   o  M :

      1-bit "Managed address configuration" flag.  When set, it
      indicates that Dynamic Host Configuration Protocol [DHCPv6] is
      available for address configuration in addition to any addresses
      autoconfigured using stateless address autoconfiguration.  The use
      of this flag is further described in [ADDRCONF].

   o  O :

      1-bit "Other stateful configuration" flag.  When set, it indicates
      that [DHCPv6-lite] is available for autoconfiguration of other
      (non-address) information.  Examples of such information are DNS-
      related information or information on other servers within the
      network.  The use of this flag for add is further described in
      [ADDRCONF].

Hi, Thank you for the link and tips. This worked for me!

V/r,
