First time ever using Cisco Packet Tracer. One place where it seems to. My project wanted me to use '10.1.1.0' Sorry for any newbie questions. This is just an example of how Classless Interdomain Routing (CIDR) works. The only complete CCNA project course using packet tracer on Udemy. For example, if your layer 2 technologies such as trunking and EtherChannel do not.

Last Update: Feburary 27th, 2019. First time ever using r. One place where it seems to go wrong is trying to manually put in the default gateway/IP address.

I have 6 subnets of my 10.1.1.0. I made my first subnet ip address 10.1.1.1 and my subnet masks 255.255.255.0.

Whenever I try to manually put in any of the other default gateways like i tried '10.1.1.65'and Im greeted with the error message that its over lapping with the g0/0. Whnever I use different IP address for all my different switches, it works, but my project wanted me to use ' Sorry for any newbie questions, appreciate any help thats given!

A little different, but the same idea: 192.168.3.0/24 has 256 IP addresses, (0-255). Stan getz library. 192.168.3.0 is the network ID.

192.168.3.255 is the broadcast ID. 192.168.3.1-254 are the usable IPs. You can split this into two /25’s. 192.168.3.0/25 192.168.3.0 (net ID) 192.168.3.127 (broadcast) 192.168.3.1-126 (usable) 192.168.3.128/25 192.168.3.128 (net ID) 192.168.3.255 (broadcast) 192.168.3.129-254 (usable) This is just an example of how Classless Interdomain Routing (CIDR) works. Other people will have much more in depth learning on it.
