• On Router C, interface Dialer0 is assigned an IP address 122.1.1.2/24.
• The Dialer0 interfaces on Router A and Router B are located on the same network segment, so
are the Dialer1 interface on Router A and the Dialer0 interface on Router C.
Configure RS-DCC to allow Router A to call Router B and Router C from multiple interfaces but
disable Router B and Router C from calling each other.
