Dear GS,
I have an interesting challenge for you. Given the setup and configurations
bellow, you are allowed to configure a tunnel between R1 and R3. You need to
reach 10.10.1.1 from R3 in just one hop.

Original Output:
++++++++++++++++++++++++++++++++++++++++++++++++
R3#trace 10.10.1.1
Type escape sequence to abort.
Tracing the route to 10.10.1.1
1 10.10.23.2 16 msec 16 msec 16 msec
2 10.10.12.1 32 msec * 28 msec
R3#
++++++++++++++++++++++++++++++++++++++++++++++++
Required Output:
++++++++++++++++++++++++++++++++++++++++++++++++
R3#trace 10.10.1.1
Type escape sequence to abort.
Tracing the route to 10.10.1.1
1 xxx.xxx.xxx.xxx 44 msec * 44 msec
R3#
