Packet Tracer Lab 11.10.1 - Host devices not working?

[jeffreywalker]

Hello!

I am still early in my CCNA education, however I believe I have subnetted this topology correctly, however, the left host devices ES47 and E122 do not wish to communicate to their respective switches and I cannot figure out why.

Both switches have Vlan1 enabled, a proper IP address for my scheme, and have default gateways of their respective ports at the router. Both PC's have IP addresses that fit the scheme, and their gateways are the router interfaces that belong to them.

East g0/0 - 192.168.203.97 255.255.255.240

ES2 Vlan1 - 192.168.203.98 255.255.255.240 DG - 192.168.203.97

E247 - 192.168.203.126 255.255.255.240 DG - 192.168.203.97

East g0/1 - 192.168.203.129 255.255.255.248

ES1 Vlan1 - 192.168.203.130 255.255.255.248 DG - 192.168.203.129

E122 - 192.168.203 255.255.255.248 DG- 192.168.203.129

The entire right side of the network can ping every other device except the host devices on the left. Everything can ping everything except for anything involving the devices on the left.

I figure it's my own bug, because I have had issues with ping in other labs in which devices not on the path (or even within 1 wire connection) just have STP packets appear without prompting.

Any help would be great, as I am going slightly insane. Thank.

Hey Jeffrey,

With a network mash the answer to 40 years subnets go up by account of 16 which means your subnet you are working in is 192.168.203.96.  With the mask of 255.255.255.240.  The next subnet would be 192.168.203.112.  Your IP address is out of range.  

Also on E122, there seems to be a digit missing after 192.168.203

If this works please mark it as the answer.  It will be my first one.

you are correct! i had a incremented a mask wrong, which led me to increment the next one wrong. thank you!
