Thanks for the reply cjunior.
But what dns listner has to do with this, also can I delegate the zone to external bind for which as per the zonerunner my F5 dns is the authorotative server. All I want is to forward all dns traffic from f5 to external bind server if the A record is not configured on F5.
As I have mentioned in the previous post that we have GSS doing the same thing and passing *.test.com to bind server.
Sorry for my ignorance on this topic as by no means I am expert on this.
Any help with the example will be appreciated.
Thanks,
Pankaj
