Configuring DNS Name Server Addresses for Subscriber Management

This topic describes the procedure for configuring DNS name server addresses at the access profile and routing instance levels. For information about configuring addresses in DHCP address pools, see the DHCP topics referenced in the Related Documentation section. For information about configuring addresses on your RADIUS server, refer to your RADIUS software documentation. The order in which the name server configurations at different levels are preferred is described in DNS Name Server Address Overview.

Best Practice: In practice, choose either the domain-name-server statement or the domain-name-server-inet statement for IPv4 addresses. They both have the same effect and there is no need to use both statements. If you do use both statements, addresses configured with domain-name-server-inet are preferred over addresses configured with domain-name-server.

To configure DNS name server addresses globally:

  1. Configure an IPv4 address.
    [edit access]user@host# set domain-name-server-inet dns-address

    Alternatively, you can use a different statement to configure an IPv4 address.

    [edit access]user@host# set domain-name-server dns-address
  2. Configure an IPv6 address.
    [edit access]user@host# set domain-name-server-inet6 dns-address

    For example, to configure multiple addresses of each type:

    [edit access]user@host# set domain-name-server-inet 172.16.25.31user@host# set domain-name-server-inet 172.16.25.100user@host# set domain-name-server-inet6 2001:db8:85a3::8a2e:370:81causer@host# set domain-name-server-inet6 2001:db8:85a3::8a2e:370:7334

To configure DNS name server addresses in an access profile:

  1. Configure an IPv4 address.
    [edit access profile profile-name]user@host# set domain-name-server-inet dns-address

    Alternatively, you can use a different statement to configure an IPv4 address.

    [edit access profile profile-name]user@host# set domain-name-server dns-address
  2. Configure an IPv6 address.
    [edit access profile profile-name]user@host# set domain-name-server-inet6 dns-address

    For example, to configure multiple addresses of each type:

    [edit access profile vrf-s-access]user@host# set domain-name-server-inet 172.20.10.01user@host# set domain-name-server-inet 172.20.100.100user@host# set domain-name-server-inet6 2001:db8:85a3::8a2e:370:ac81user@host# set domain-name-server-inet6 2001:db8:85a3::8a2e:370:71bfd
