Hi Everyone,
This question may look stupid but its importance is vital to me as I am learning this technolgy my question is this:
I have configure 5 vlans on my L3 switch: - vlan 10 ip address 192.168.10.1 255.255.255.0
- vlan 20 ip address 192.168.20.1 255.255.255.0
- vlan 30 ip address 192.168.30.1 255.255.255.0
- vlan 40 ip address 192.168.40.1 255.255.255.0
- vlan 50 ip address 192.168.50.1 255.255.255.0
Now, what is the subnet summarisation of all these ip addresses or what is a unique ip address summarising all these subnets.
Best regards,
BEN

A /19 equates to 32 Class C networks. Not enough. So you would need to summarize with a /18 (255.255.192.0) which includes 64 Class C's. The summarization would be:
192.168.0.0 255.255.192.0
That includes addresses from 192.168.0.1 through 192.168.63.254 (not including the all zeros network number and all ones broadcast addresses).
