One Router-Two Interfaces--Same IP-- Is it Possible ?

Hi guys,

 

 

Before writing "NO, IT IS NOT POSSIBLE " , please have some patience and read this entire confusion of mine.

 

 

I was learning how to configure a router using SDM EXPRESS on 1841 model.

 

 

While Configuring, a serial WAN connection, there are three options to get an IP for the serial interface.

 

 

1. Static IP Address

 

 

2. IP Unnumbered

 

 

3. IP Negotiated.

 

 

 

 

 

My Question is about OPTION 2 -


IP UNNUMBERED. So I am leaving the details of options 1 and 3.

 

 

IP Unnumbered option is available with Frame Relay, PPP and HDLC encapsulation types. If I select this option for , say, S0/0/0, the GUI shows another listbox labeled as "UNNUMBERED TO " which contains the names of fa0/0, fa0/1, S0/0/1, VLAN1. So it means, we can set the serial interface address of a router to match the IP address of one of the router's other functional interfaces.

 

 

I am little bit confused ....
