For IPv6 hosts, a maximum of three recursive DNS server
addresses can be configured along with their respective lifetimes.
The configured IPv6 host uses the specified recursive DNS server address
for DNS resolution where the IPv6 host’s address is autoconfigured
through an IPv6 stateless address and where there is no DHCPv6 infrastructure
available.
To configure a recursive DNS server address on IPv6 hosts,
follow these steps:
- Configure the recursive DNS server address for the IPv6
host.
[edit protocols router-advertisement]
user@host# set interfaces interface name dns-server-address address
For example, to assign IPv6 address abcd:1::1 as the recursive
dns server address to interface fe-1/0/1:
[edit protocols router-advertisement]
user@host# set interfaces fe-1/0/1 dns-server-address abcd:1::1
- Configure the lifetime to specify the time in seconds
for which the recursive DNS server address remains valid.
[edit protocols router-advertisement interfaces interface name dns-server-address address]
user@host# set lifetime seconds
For example, to specify a lifetime of 60 seconds for the recursive
DNS server address:
[edit protocols router-advertisement interfaces interface name dns-server-address address]
user@host# set lifetime 60
The default value of the lifetime of the configured recursive
DNS server address is 1800 seconds.
