Hello Tony,
Yes, but there is the Recursive Routing problem with OSPF... And since you
are not allowed to add ip addresses or static routes... Please try to solve
this, it's funny :)
Thanks.
Antonio

Am I missing something here?
Would a GRE tunnel from loopback to loopback give you the desired results?

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#
