i have connected two routers togetherby using packet tracer 4.11. routers dont ping each other. the configurations is the problem for me. how do i configure the routing?? so that if i send data from 1st router's network to the 2nd router's network, it gets there.
how do i do that...
i am really sorry for my words. its really really hard to explain the situation in words unless you actually see the networks. i am trying my best

I AM DESPRATE TO KNOW THIS
here are the details...
i have a network 192.168.1.0 at router's interface 192.168.1.1.
i have other network 192.168.2.0 at the same router's interface 192.168.2.1
router external interface (the one that connects local networks to external network) is 192.168.8.1
this is one router
on other router, i have network 192.168.3.0 at interface 192.168.3.1
i have ohter network 192.168.4.0 at the same router (router #2)'s interface 192.168.4.1
. Router #2's external interface is 192.168.9.1
now i want "192.168.8.1" (Router #1's external interface) to forward data to "192.168.9.1" (Router #2's external interface).
i need command for that.
when i try to ping a host on network 192.168.4.0 for a host on network 192.168.1.0, it says "Reply form 192.168.1.1 (router #1's internal interface) Destination Host Unreachable"
THIS IS ALL I CAN PROVIDE
PLEASE PLEASE HELP ME
I BEG U!
