sorry i cant find out how to edit my first post but this is what i came up with but still having problems getting host 2 to ping host 1 and getting both hosts to ping the gateway --->



I used a subnet of 255.255.255.192

Here are the IPs and subnet I'm using and i have listed it from left to right --->


__________________________________________________ ___

Host 1 :

IP(192.168.16.2) - Sub(255.255.255.192)
Gateway : 192.168.1.1


DALLAS SWITCH


Dallas Router :

IP(192.168.16.1) - Sub(255.255.255.192)
Serial 0/0/0 : IP(192.168.16.193) - Sub(255.255.255.192)

Static : IP(192.168.16.64) - Sub(255.255.255.192) - Next Hop(192.168.16.194)



Raleigh Router :

IP(192.168.16.65) - Sub(255.255.255.192)
Serial 0/0/0 : IP(192.168.16.194) - Sub(255.255.255.192)

Static : IP(0.0.0.0) - Sub(0.0.0.0) - Next Hop(192.168.16.193)


RALEIGH SWITCH


Host 2 :

IP(192.168.16.66) - Sub(255.255.255.192)
Gateway : 192.168.1.1

It will ping from host 2 all the way to the Dallas Router but it will not go to Host 1 for some reason.

Also when I try to ping the gateway for host 1 for some reason it won't ping and times out and when I try to ping the gateway for host 2 it says it can't be reached.

From left to right it goes

Host 1
Dallas Switch
Dallas Router
Raleigh Router
Raleigh Switch
Host 2


Please let me know if you have any ideas any help will but super appreciated!

I think i found that its the gateway but i was wondering if anyone could help me figure out what gateway i need and how to figure that out so i can learn.

Thanks everyone!

Your default gateway on Host 1 should be 192.168.16.1 (Dallas router's interface on 192.168.16.0/26). The default gateway on Host 2 should be 192.168.16.65 (Raleigh Router's interface on 192.168.16.64/26).
