Static Routing

[Makiesto]

Hi,
I'm new in cisco packet tracer and have some problems with this topology. I need to configure static routes for this network. Can someone explaine me how to do it? Thanks in advance.

Thanks for your reply, however i have done this. My problem is, I cannot ping from 172.164.100.0 to 172.160.200.0. I think that i should configure routing (static). How should i do this?

Hello,

Static routing is nothing more than letting a router know (manually) where a network lives. You configure network statements on each router pointing to each network in your topology.

For example:

R3 needs to know where to go to get to networks 172.164.100.0/24 and 172.160.200.0/24. So you would configure static routes as such.

ip route 172.164.100.0 255.255.255.0 172.16.2.2 <- this says to get to network 172.164.100.0/24 go to the next hop 172.16.2.2. It knows how to get to that network because its directly connected. You will need to create static routes on each router for both networks pointing to a next hop of their neighbor until it reaches its destination.

The second route on R3 would look like this:

ip rotue 172.160.200.0 255.255.255.0 172.16.1.98

You will need to add these network routes to each router and their next hop as in the example above and you should have connectivity.

Hope this helps

Thank you for you answer, i did it, but pcs from 172.164.100.0 /24 still cannot ping to pcs from 172.160.200.0 /24 and vice versa. Do you have some suggestions where is the problem?

Do the wireless routers have a default route ?

Attach your PacketTracer file here, ZIP It first.

 Let me see If static routing is the only problem

All good with your static route.  

The problem is related to the limitation of Wireless router. This router is meant to be used as a home wireless router and does not allow much configuration. You can not add route on it, for example. 

The solution I gave to prove the static routes among all routers is working properly was configure the LAN interface of the Wireless rotuer instead the internet interface. This way, I can use the wired router 1841 as a gateway and therefore, I can ping end to end.

Consider that packet through your Wireless router R1 is source NAT. Meaning IP SOURCE 172.164.100.3 to IP DESTINATION 172.160.200.2.... the Wireless routeur R1 will nat the IP source to 17.16.2.2....
