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

    Chetan

       

      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 ....

       

       

       

       

       

      NOW you can write your comments
