I am using packet tracer to connect two routers on different subnets. using serial cable. one side DCE and other DTE.
the above is not working. but when I change the 2nd router ip to same subnet 192.168.10.30 it works.
The packet tracer file is attached. Please help.
Routers directly connected must be on same subnet to communicate
you have 192.168.10.0 network subnetted into 8 subnets (networks) with 30 hosts per each:
Magic number is 32, so start at 0, add 32, aka
and so on till
just figured routers must be on same subnet. thanks.
so the seial connection is wasting one subnet i guess.
yep, but all interfaces on 1 router must be in separate networks.
My suggestion is to not play with subnets at beginning; don't use subnetting at all; use classfull networks (/8, /16, /24); it got me confused when I studied for ccna.
I build all my labs with classfull networks first; then, I "re-used" them by dividing networks into smaller prtions (aka making subnets; subnetting).
oh well just configured one VLSM /30 (serial) , /27, /26, /25 using EIGRP. its not hard only if the instructions was clear. thanks.
i am having a different sort of prob...got 2 routers...i have connected them using serial interface...layer 1 is up but line protocol in down...can't figure out the prob...they are on the same network
the network has other components as well
can't figure out why this is happening...could u help
well i didn't set the clock on the DCE side just realised it
well, sometimes it helps to take a brake; step away from the problem and comeback in few minutes, run it again to see if you miss something;
something are obvious but for some weird reason people seem to miss it;
It's not mandatory if we use PPP and the peer-neighbour route is not disabled.
But you're right for CCNA learning purposes.But if the OP had used PPP it would have worked without he realized it or he would maybe have realized the subnet mismatch but wondered how this is possible.
u r right...hey...could you provide some link for ccent mock exams or something like that??so that i can have an idea of the type of questions that they ask in the real exam
There are some stuff on CLN, I used this link to get an overview of types of questions
I have also used CCENT/ICND1 Exam Guide (2nd Edition) from Wendell Odom it looks like there is 3rd Edition coming out next week.
Hope this Helps,
