+# Let's suppose we have two DNS servers: 8.8.8.8 and 8.8.8.9.
+# Our purpose is to get the DNS load balanced for the DNS servers.
+# Example: within the "post-auth" section add the following stuff:
+    if ( "%{rand:2}" == "0" ) {
+        update reply {
+            # delete all the DNS attributes
+            VasExperts-DHCP-DNS !* ANY
+            VasExperts-DHCP-DNS = "8.8.8.9"
+            VasExperts-DHCP-DNS += "8.8.8.8"
