Hi Group,
Task ask us to configure a routers so that all traceroute traffic to that router, answers must be from loopback 0. I tried the answer but is not working, I am not seeing the hits in the route-map for nat translation, not sure where I am doing mistake. If anybody completed this task any help is appreciated.

commands:
=========================
interface Loopback0
ip address 150.1.3.3 255.255.255.0
no ip directed-broadcast
ip nat outside
ip ospf network point-to-point

interface Loopback1
description ARBITORY
ip address 1.1.1.1 255.0.0.0

route-map POLICY permit 10
set interface Loopback1
!
