Perform this task to
verify the Overlapping Prefix feature in the LISP network. In this example,
there are four routers: MSMR, xTR2, xTR3, and xTR4. Each router has an
interface connection in the same subnet (RLOC space) 10.0.0.0/24. The following
are the IP addresses of the routers:
Router

MSMR
|

10.0.0.2
|
xTR3
|
10.0.0.3
|
xTR4
|
10.0.0.4
