C 192.168.1.0/24 is directly connected,
Vlan10
C 192.168.2.0/24 is directly connected,
Vlan20
C 192.168.3.0/24 is directly connected,
Vlan30
Take
6 systems and rename as the following figure.
3. Using the Config tab in Packet Tracer,
configure the IP address, mask, and default gateway on each host.
PC – 192.168.1.10 255.255.255.0 Default gateway 192.168.1.1
PC – 192.168.1.20 255.255.255.0 Default gateway 192.168.1.1
PC – 192.168.2.10 255.255.255.0 Default gateway 192.168.2.1
PC – 192.168.2.20 255.255.255.0 Default gateway 192.168.2.1
PC – 192.168.3.10 255.255.255.0 Default gateway 192.168.3.1
PC – 192.168.3.20 255.255.255.0 Default gateway 192.168.3.1
CCNA#sh ip route.
Now try to ping from PC
192.168.1.10 to 192.168.1.20 and 192.168.1.10 to 192.168.3.20.
