LAB 1-2: IPv4 Addressing

You are the network administrator at Ranet, and
have to config the router “Ranet-BR” via Console
Terminal as below:

1. enable interface Se0/0/0 and set IP address
/Subnet Mask that can connect with router
“Ranter-HQ” at 192.168.0.254/30

2. enable interface Se0/1/0 and set IP address
/Subnet Mask that can connect with router
“Ranter-BR1-1″ at 192.168.0.30/30

3. The Headquater has given IP address
range 192.168.0.0/27 for the network
behind our router, then you have to:

     3.1 enable interface Fa0/0 and set
     IP address/Subnet Mask to be the
     last IP of this subnet that has
     10 host as members.
If the configuration is correct, Host1 in each subnet
must be able to ping to Ranet Server at 192.168.0.33

 ============= The End ===================

Solution:


192.168.0.0/27
*10 host:
int fa0/0 : 192.168.0.0/28  --- use last ip
*5 host:
int fa0/1 : 192.168.0.16/29 -- use last ip
------------------------------
int se0/0/0 : 192.168.0.254/30 -- use first ip
int se0/1/0: 192.168.0.30/30 -- use first ip
