Dns Priority
Test suite to check DNS service priorities
Valid Address
Description
Configures a simple, valid address and checks the DNS can resolve it. There is no priority involved as a single address is in use.
Scenario
Step 1: Set the following configuration in DUT1 :
set interfaces ethernet eth0 address 10.0.0.2/24 set service dns forwarding record host teldat.com ipv4-address 172.24.0.11 set service dns forwarding record host teldat.com ipv6-address 'ff00::dead:cafe' set service dns resolver local set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'
Step 2: Set the following configuration in DUT0 :
set interfaces ethernet eth0 address 10.0.0.1/24 set service dns forwarding logs set service dns forwarding name-server 10.0.0.2 set service dns resolver local set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'
Step 3: Ping IP address 10.0.0.2 from DUT0:
admin@DUT0$ ping 10.0.0.2 count 1 size 56 timeout 1Show output
PING 10.0.0.2 (10.0.0.2) 56(84) bytes of data. 64 bytes from 10.0.0.2: icmp_seq=1 ttl=64 time=0.428 ms --- 10.0.0.2 ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 0.428/0.428/0.428/0.000 ms
Step 4: Run command show host lookup teldat.com type A wait 0 at DUT0 and check if output contains the following tokens:
172.24.0.11Show output
teldat.com has address 172.24.0.11
Step 5: Run command system journal show | cat at DUT0 and expect this output:
