Static Route Set But Can't Ping The Other Side

[msen25898]

Hi Everyone,

I hate asking for help but I've been at this all day and I can't seem to resolve. It's the end of the semester. I'm not asking for the answers, just need help pointing out what I'm doing wrong. I hope you can see the picture I've attached. So basically I have to Ping the Backbone Host from Host 6.3 and Host 7. I can ping to 192.168.2.254 on F0/0 on Router2 but not the other side. But Router7 can't ping Router2. I don't know how that's possible. I have OSPF set up for Router2 & Router7 as well as Static routes. Here's the config

Does anyone have any idea what I'm missing? I thought the Static route would at least allow me to do it.

Hello

From what you have shown  r2-r7 and r7-r8 don't share a common subnet unless that is the switch's interconnecting those rtrs do this.

[Martin L]

Routers should be on the same subnet; aka share network in order to communicate.  unless your LAN2 switch is Layer 3, capable of routing,  router 7 should have IP on  192.168.10.x /24 network. then, both routers can exchange info like routes among themselves.  Is LAN2 switch a L3 or L2 device? 

I would recommend getting Packet tracer, free from Net academy after free registration.  they have some samples and there are lots of labs for PT available here and on the Internet.

see https://www.netacad.com/courses/packet-tracer

note: if get free Packet tracer, there are samples of labs under File >Open .Sample lab.
good luck and have fun !

Hi,

According to the simulator, it's a Cisco 2811 switch. We haven't touched on layer 3 routers and their settings. Here's the entire network. I would assume that Router4 and Router3 share the same configurations. From Host 5, I am able to ping the Backbone host. It is set up with OSPF and it can get to the Backbone host in both directions. Host 3 can also ping the Backbone host as well. 

IP address on F0/1 on Router7 was left blank for me to assign 

As well as both serial ports on Router 5 &6 and F0/1 on Router5

All host on the left side of Router2 can ping the Backbone host and up to F0/1 on Router2. All host on the right can ping up the right side on Router2

I should also mention that all other IP addresses on the router interfaces were set  for the assignment by the instructor. It's not mentioned if we can change them but in previous assignments, we've never had to change them. 

[Martin L]

I think F0/1 on Router7 should have 192.168.2.x /24 IP not .10.254/24
Router 5 Fa0/1 should be same network as Router3 with IP on 192.168.3.x /24
Layer 2 switches are just passing traffic in the same vlan, not between vlans. whereas Layer 3 switches are like routers they can route traffic between vlans.

Ok so I tried changing the interfaces to what you've suggested but still nothing. I them back and played around some more. I feel there's some kind of voodoo magic going on. The simulator probably isn't reflective of what actually happens in real life. With the settings how they are, I am able to get Host 7 to ping Host 5 now. I can't ping the Backbone Host though. I have every step done now except be able to get Host 6.3 to ping the Backbone Host. Out of curiosity, I changed its IP address to 192.168.6.51 but still nothing.

I actually downloaded that yesterday as I was working on this assignment but haven't gotten much time on it. we've been using Network Visualizer. I plan on playing with it more though thank you
