New IP PC Configuration
Tasks on the PCs
Configure Network Card to “Labor LAN”
IP Address, Subnetmask
For PC1, PC2, PC7, PC8
Default Gateway is IP address of your own PC´s ethernet interface
usage of proxy ARP because on this network there are two routers
For PC3, PC4, PC5, PC6
Default Gateway is IP address on interface e0 of your corresponding
router Rx
PC3 -> R3, PC4 -> R4, PC5 -> R5, PC6 -> R6

Create Loopback Interfaces
On all routers
router(config)# interface loopback 0
router(if-config)# ip address 172.255.X.X 255.255.255.0
x = is the corresponding Router Number
these addresses will be immediately distributed by RIPv2 after
issuing the following command
router(config)#router rip
router(config-router)#network 172.255.0.0
router(config)# interface loopback 1
router(if-config)# ip address 223.X.X.X 255.255.255.255
x = is the corresponding Router Number
these addresses will not be distributed by RIPv2 because there is
no corresponding “(config-router)#network” command
we will use these addresses later for generating Router OSPF-IDs
