Hands-on Lab
103
Using IP Unnumbered
Following are the steps required to complete the lab:
1.
Physically connect the routers, as shown in the diagram.
2.
Configure a loopback interface on RouterA with an IP number of
172.16.1.1 and a 24-bit subnet mask:
hostname RouterA
interface lo0
ip address 172.16.1.1 255.255.255.0
no shut
3.
Configure a loopback interface on RouterB with an IP number of
172.16.2.1 and a 24-bit subnet mask:
hostname RouterB
interface lo0
ip address 172.16.2.1 255.255.255.0
no shut
4.
Interconnect the serial ports on the routers with a serial crossover
cable (RouterA connected to the DTE side of the cable and RouterB
connected to the DCE side of the cable).
5.
For RouterA, configure for RIPv2:
router rip
version 2
network 172.16.0.0
Loopback Interface: Io0
172.16.1.1/24
Interface S0
DTE
IP unnumbered
Interface S0
DCE
IP unnumbered
Loopback Interface: Io0
172.16.2.1/24
RouterB
RouterA
