    Hi,
    I want to set up a internetworking environment:

    The Network Topology:

    Internet ----R1 ---LAN1---R2----IPLC(leased Line )----R3----LAN2


    1. 3 routers: R1, R2, R3
    2. R1 = ADSL Router( can not be touched ), the LAN IP = 202.27.9.16/28
    IP = 202.27.9.17/28
    Default = 202.27.9.17
    DNS = 202.27.9.19
    3. R2 = IPLC Router, LAN IP = 202.27.9.18; WAN IP = 192.168.1.253/24
    4. R3 = IPLC Router, WAN IP = 192.168.1.254/24, LAN IP = ??

    How can I configure the R2 & R3 to be a bridge, so that I can use the
    LAN1 IP Address from the LAN2 IP( LAN1 + LAN2 = LAN1 )?

    Thank you so much

    It's a very simple thing and it shows you haven't even tried to look for
    the solution on CCO (www.cisco.com). Search for CRB or IRB (after
    reading both, you'll see what suits your needs).

    Yes, it is quite simple to configure the IRB bridging, I did it from
    the cisco's instruction .

    Thanks a lot
