Problem with very simple network

Jan 05, 2006 4 Replies

Hi



I have a problem with routers Cisco IOS 2600 on simulator Routersim. I have connected 2 routers with serial interface and configured IP but when I ping from the first router to the second the response is 100% lost packets. What should I do? Why my routing table must by? I have 192.168.20.1/24 on the first router and 192.168.20.2/24 on the second router.


ensure that you have set clocking on the dce side. Also make sure that you have set up the connectors correctly within boson.

int serial 0/1 description routerA encaps ppp ip addr 192.168.20.1 255.255.255.252 (or 0 whatever you prefer) no shut

int serial 0/1 description routerB encaps ppp ip addr 192.168.20.2 255.255.255.252 (or 0 whatever you prefer) clock rate 64000 no shut

I had some problems with Boson netsim at first, I found that if i changed the 2600 model that I was using I fixed it.

Let us know how you make out.

Thanx it works, but I have another problem. If I connect third router to the routerA with serial0/0 172.16.1.1/16 and I will go to the routerB and I ping 172.16.1.1 then result is ok only when I add on routerB: ip route 172.16.1.0 255.255.0.0 192.168.20.1

but

ip route 172.16.0.0 255.255.0.0 192.168.20.1 doesn't work

172.16.0.0/16 is a network address. Remember can't use all 0's or all 1's for hosts

John

Can you give me some correct addresses example for my routerC (172.16.1.1/16) and table IP routing?
