HCIA configuration instance (ENSP)

The experimental requirements

1. Network wide accessibility
2. The addresses required in the topology are all based on 192.168.0.0/24 Divide the income
3. All use static routing
4. RB Loopback needs to be summarized

analysis

The network segment required for the whole network is 9 paragraph , Then borrow from the host location 4 position

192.168.0.0/28
192.168.0.16/28
192.168.0.32/28
192.168.0.48/28
192.168.0.64/28
192.168.0.80/28
192.168.0.96/28
192.168.0.112/28
192.168.0.128/28

Among them, the 192.168.0.0/28 Into three loopback network segments

192.168.0.0/30
192.168.0.4/30
192.168.0.8/30
