OSPF Issue

amb1s1amb1s1 Senior MemberMember Posts: 408
Hi I'm going crazy with this problem. I'm using Netsim 6. I have the following topology:

2 Router + 2 switch + 2 PC

PC_1
Switch_1
Router_1
Router_2
Switch_2
PC_2

Roouter_1

int s0
ip address 192.168.10.1 255.255.255.0
clock rate 64000
Clock rate 64000

int E0
ip address 192.168.20.1
no shut

Router ospf 1
network 192.168.0.0 0.0.255.255 area 0


Router_2

int s0
ip address 192.168.10.2 255.255.255.0
no shut

int E0
ip address 192.168.30.1
no shut

Router ospf 1
network 192.168.0.0 0.0.255.255 area 0

PC_1

ipconfig /ip 192.168.20.2 255.255.255.0
ipconfig /dg 192.168.20.1

PC_1

ipconfig /ip 192.168.30.2 255.255.255.0
ipconfig /dg 192.168.30.1

I can ping 192.168.10.2, 192.168.20.1 and 192.168.30.1 from router_1 and
I can ping 192.168.10.1, 192.168.20.1 and 192.168.30.1 from router_2, but I'm not able to ping PC_1 from Router_2 or PC_2 from Router_1. Can someone explain me what I'm doing wrong.

    Are you running any firewall on the PCs?

    If so, disable it.

    I don't think Boson Netsim has any firewall option

    Ah - I was thinking real PCs.

    Post your actual configs, route tables, and how far you can ping out from each PC.
  • dtlokeedtlokee Village Idiot Member Posts: 2,378 ■■■■□□□□□□
    Can you ping from the pc to the first hop router?

    The only thing I see is the no shut is missing on the serial 0 of Router 1. I would check to see that the OSPF neighbors are established and see what networks are being advertised with "show ip protocols".

    If all that is good, then I would suspect it's a problem with the simulator, they can be problematic.

    can the hosts ping their default gateway?


    Also can you ping PC1 from router1 and PC2 from router2?

    It may just be a bug in the simulation.
    There is no place like 127.0.0.1 BUT 209.62.5.3 is my 127.0.0.1 away from 127.0.0.1!

    amb1s1,

    How come your E0 interfaces on Router_1 and Router_2 do not have subnet masks?

    all the interfaces are up up. I think this is a Sim problem.

    well from what you CAN ping it looks like each router has the neighbor's ethernet interface in the routing table. So if router1 has a route for router2's ethernet network, router1 should be able to ping 192.168.30.1 and you say it can. So knowing that, you should be able to ping the host as well. So this looks like a error in the simulation. If you can ping the hosts from their local routers, like if Router1 can ping PC1, then it is definately a bug.

    Do you configure additional VLANs on Switch_1 and Switch_2 above and beyond the defaults?

    amb1s1,

    If Boson NetSim is the same as Boson ExSim, then the inability to highlight may be Boson electronically enforcing their copyright by requiring you to incur the hassle of manual retyping.

    amb1s1,

    When you mention "...it should have the default config." does that mean that you haven't verified the default config? What are the defaults for a Cisco Catalyst 2950 switch?

    Go to "File" and select either "Save Single Device Config" or "Multi Devices Configs". You will then be prompted for a name to save your config as.

    I just downloaded the Boson Demo NetSim and had no trouble saving my configs. Also, I was able to copy what was in Boson's "Hyperterminal" interface by highlighting what I wanted to copy, then right clicking and selecting 'copy'.

    amb1s1, Boson netsim is much bugged, also me I have spent much time before realize that. If You have set up correct default gateway on PC_1 and PC_2, i think the lab is right.

    I use netsim and it's absolutely ridden with bugs... it's actually a bag of sh*te. It does have it's uses... if only for having somewhere to type in commands. If I'd paid for it I'd be seriously p*ssed. Your better off trying to get some cheap equipment off ebay mate.
