Kings,
What in the scenario or question will make it one or the other (null0 or loopback)? Johan From: [email protected] [mailto:[email protected]] On Behalf Of Kingsley Charles Sent: 03 March 2010 16:55 To: [email protected] Subject: [OSL | CCIE_Security] Lab 4A - Section 4.5 - Overlapping subnets Hi all For this lab, the solution has a loopback interface created with the IP address of the translated IP address. By doing this, we waste one address on each. Instead, I think the following will be the best solution without using a loopback. ip route 10.44.44.0 255.255.255.0 null0 on R4 ip route 10.40.40.0 255.255.255.0 null0 on R6 These routes will trigger the routing update for the networks that will be translated. With regards Kings
