[j-nsp] Setting source address for local DNS queries on JunOS (8.5R1.14)?

[Johannes Resch]

Hi list,

is it possible to specify which local IP address a router will
use for originating DNS queries, either globally or per name server? 
JunOS is 8.5R1.14 on J6350.

Couldn't find anything related in the tech docs, and there don't seem
to be suitable config options in the "system name-server" hierarchy.

Per default, it seems as if the router picks the numerically lowest IP 
address as source IP (in this particular case, there is no IP address 
configured on the loopback interface).

Regards,
