Q. Is it possible to have duplicate ip addresses for two serial interfaces
that belong to the same router?
A. Yes, duplicate ip addresses are allowed on serial interfaces. It is a
more efficient way of bundling links together (ie. MLPPP) and also a better
way to preserve address space. Change the encapsulation from the default
HDLC to PPP in order to assign duplicate ip addresses.

Subject: Re: IP address on serial interfaces of a router
What is the logic behined that I can assign 10.0.0.1/24 (exactly the same ip
address) on two serial interfaces of a single router???
R1#sh run
---output omitted---
interface Serial1/0
ip address 10.0.0.1 255.0.0.0
serial restart-delay 0
!
interface Serial1/1
ip address 10.0.0.1 255.0.0.0
serial restart-delay 0
Wont the router be confused when it will forward traffic for
10.0.0.0/24network??
Thanks and regards,
