Recursive DNS server addresses

Recursive DNS server (RDNSS) addresses is an IPv6 router advertisement (RA) feature that allows IPv6 devices to advertise recursive DNS server addresses and lifetime values to IPv6 hosts in a local area network.

RDNSS contains the addresses of recursive DNS servers that help in DNS name resolution and can be configured on any network that supports neighbor discovery (ND). The configured recursive server addresses are advertised by devices through RA messages, and are used to translate domain names into IP addresses.

  1. Configuring recursive DNS server addresses
    RDNSS addresses allow IPv6 devices to advertise recursive DNS server addresses and lifetime multiplier values to IPv6 hosts in a local area network. The following task configures two DNS server addresses to be advertised for an Ethernet interface in router advertisement (RA) messages, and sets separate lifetime multiplier values for each of the DNS server addresses configured.
