Creative Routing ContestWell, we made it through the first CCNA scholarship and now it's time for something everybody can participate in again. For this one, a topology will be provided and it will be up to the contestants to configure the routers. The object is to use your creativity to get a packet to traverse every router in the topology before eventually arriving at the far end. The topology is simple, but the possible solutions are many.
Topology
Interface ConfigurationsR1 ConfigCode:
interface Loopback0
ip address 10.1.1.1 255.255.255.255
!
interface FastEthernet0/0
description R3 F0/0
ip address 10.1.2.1 255.255.255.0
no shutdown
R2 ConfigCode:
interface FastEthernet0/0
description R3 F0/1
ip address 10.1.3.1 255.255.255.0
no shutdown
R3 ConfigCode:
interface FastEthernet0/0
description R1 F0/0
ip address 10.1.2.2 255.255.255.0
no shutdown

R4 ConfigCode:

description R3 F1/0
ip address 10.1.4.1 255.255.255.0
no shutdown
R5 ConfigCode:
interface Loopback0
ip address 10.1.6.1 255.255.255.255
interface FastEthernet0/0
!
description R3 F2/0

Example Trace Route OutputCode:
R1#traceroute 10.1.6.1 source loopback 0
Type escape sequence to abort.
Tracing the route to 10.1.6.1
1 10.1.2.2 40 msec 44 msec 4 msec
2 10.1.3.1 40 msec 4 msec 28 msec
3 10.1.3.2 40 msec 16 msec 12 msec
4 10.1.4.1 40 msec 4 msec 32 msec
5 10.1.4.2 20 msec 12 msec 16 msec
6 10.1.5.1 56 msec * 72 msec
Rules?- After issuing the command "traceroute 10.1.6.1 source loopback 0" on R1, the resulting packets must cross all routers in the topology.
- The physical interfaces, topology, and pre-defined IP addressing can not be changed.
- ZIP your router config *CHANGES* and resulting traceroute and email them to steve at spish dot net. Include your forum username.
- The contest ends on 4/6/2011 at 2:00PM CST.
The JudgesOther Details- Blog, Facebook, and tell your geeks friends about this. The more the merrier.
