Junos: resolve DNS through mgmt_junos
Closed, ResolvedPublic
Actions

Description

Related to T269340 and T320244

DNS resolution works through mgmt_junos only since 19.2R1.
Once all routers are upgraded we can configure it and revert to having syslog targets and maybe NTP targets as hostnames instead of IPs.

Once done we should be able to remove the loopback filter term allow_dns as well.
