subnets at the maximum?
Type the correct value in each box below.
Answer:255.255.254.0 2.Using a class C network address your company needs 5 subnets with at least 18 hosts per subnet. What
would the subnet mask be for this network?
Answer: 255.255.255.224 实验步骤:
1.
config term
intface e0
ip address 192.168.71.17 255.255.255.240
no shutdown
intface s0
ip address 192.168.71.33 255.255.255.240(掩码不要大意)
clock rate 64000(56000)
no shushutdown
^Z
copy run start
show ip protocol(看看是否配上) 2.
show run
config term
router rip
network 192.168.11.0
network 192.168.8.0
^Z
copy run start
show ip route(查看路由表)
