In packet tracer I'm unable to get proper communication

[stephdangerfield]

So in packet tracer I was tasked with making subnet 1 and subnet 2's PC's speak with each other which went well at first. Then I was supposed to choose if I wanted to implement DHCP. Did that on Network 3. Everything functioned. Then I was tasked with making Subnet's 1 and 2 (which together are now Network A) talk to Network3. There was no router or server there in Network3 but I added them so I could have DHCP and so that I could route Network A to talk to Network3. Nothing is functioning right now. The routers seem to be able to talk but I can't get the PCs from Network A to talk to Network3 and now subnet 1 and subnet 2 are no longer functioning as Network A!

Hi @stephdangerfield ,

Here are few observations.

1. On the router connected to network 3

1.1 You need to change the ip address on se2/0 to 20.0.0.2/8, as it is connected to se3/0 with address 20.0.0.1/8

1.2 interface se3/0 is not connected to anything, so you should remove the ip address from it and shut it down.

1.3 You should only include the local networks under

router rip,

as follow:

router rip
network 20.0.0.0
network 192.168.11.0

1.3 You can remove the static routes as rip will be used to propagate routes.

2. On the router connect to subnet 1 and 2

2.1 You should configure only the local networks under

router rip,

as follow

router rip
network 10.0.0.0
network 20.0.0.0
network 192.168.1.0
network 192.168.5.0

2.2 you can remove the static routes, as rip will be used to propagate routes

3. On router connected to Server-PT

3.1 You should include the local networks under

router rip

as follow:

router rip
network 10.0.0.0
network 172.16.0.0

3.2 You can remove the static routes, as rip will be used to propagates updates.

4. Make sure that all workstations are configured with the proper

default gateway

(192.168.1.105 for subnet 1, 192.168.5.105 for subnet 2 and 192.168.11.10 for network 3). This applies to both static and DHCP configuration. For instance, the pool on the DHCP server for network 3 has the

default gateway

set to 192.168.10.1 and needs to be changed. You will need to run

ipconfig /renew

on the workstations in network 3 after making the change on the DHCP server.

Thank you I will do all of this asap!

OK I'm still having issues. I implemented all of the changes and I'm still unable to get them to communicate. What am I doing wrong?
