I began this lab with the intent to
discover how I might include the same subnet in several places in the
same network infrastructure in such a way as to not cause any
conflict.
I've also included the following:
router-on-a-stick (R7)
NAT (PAT) (R1 R2)
mutiple routing protocols; RIP, OSPF
and EIGRP.
2-way route redistribution from/to OSPF (R1 R2)
PPP chap authentications. (R2 R6)
Frame Relay
10.0.0.0/29 is found in the RIP domain;
10.0.0.0/30 is found in the EIGRP domain.
The core OSPF domain should not have
any route to the above 10-space.
All subnets should be pingable from
everywhere in this network infrastructure EXCEPT
the already mentioned 10-space.
Feel free to attempt to put this lab
together in any way you see fit. Use my configs as a helper in case
you get stuck. Good luck!
Cheers,

Check out R5's routing table. It shows
all subnets in this network EXCEPT the 10.0.0.0./30 subnet in the
EIGRP domain.
