CSCvx06532 - PI 3.9 - DNS IP address - not updating under System Monitoring Dashboard it shows only 127.0.0.1

It is correct was PI is showing in GUI, what is not correct is that the “show running-config” is displaying nameserver which are not configured….

 

Underlying linux name server configuration in my case:
ade # cat /etc/resolv.conf
# Generated by dnssec-trigger 0.11
domain notimportant.net
search notimportant.net
nameserver 127.0.0.1
ade #

 

I think manually adding the nameserver to resolv.conf and restarting PI is going to fix the issue, I haven't done that until now, just informed my service provder.

Hello community,

it's not a bug it's a featrure:

DNS Enhancements:
Prime Infrastructure 3.9 has brought security to DNS traffic by implementing DNS Security Extensions (DNSSEC). This is enabled by default and can be controlled through new Admin CLI option - 'ip dnssec'.

 

Disabling dnssec was the solution in my case:

hostname/admin# conf t
Enter configuration commands, one per line. End with CNTL/Z.
hostname/admin(config)# no ip dnssec

hostname/admin(config)# exit
hostname/admin# write memory
Generating configuration...
hostname/admin#

Hi, had the same issue, just after migration of our dns servers to w2k19.

"no ip dnssec" on prime solved the issue.

thx to all.

br, Thomas
