Hi Brian,

I tried that too, but it seems that in a lab environtment that that solution
would violate the rule of only placing an interface under the routing process
that is specified in the requirements...I grabbing straws here, because I'm
afraid of losing points on the exam for doig this.

Quoting Brian Dennis <brian@labforge.com>:
