cant ping switch to routers

[Opaco95]

Still learning the ropes of networking, please if someone can help me

this is in packet tracer

Problem:

I cannot ping wireless routers from the switch and clients can't either, although can ping the radius server from clients but not switch to radius?

Configuration:

Ground Router - WAN IP: 192.168.1.5

Level 1 Router - WAN IP: 192.168.1.6

Level 2 Router - WAN IP: 192.168.1.7

Level 3 Router - WAN IP: 192.168.1.8

Radius server - 192.168.1.2

Straight through cables running to WAN uplinks on routers

Each router has it's own LAN configured

Switch is configured at layer 2.

When in simulation mode, ping packets get through to the router although are dropped at router?

Completely stumped, and not sure where to go from here as I am still learning

Any help would be greatly appreciated,

Hello,

post the zipped Packet Tracer project (.pkt) file...

[Opaco95]

thank you, much appreciated

seems I cant attach directly to this post but have uploaded to my google drive

Hello,

Packet Tracer does not allow wireless routers to respond to ICMP requests. If that is your only issue, that PT feature would explain that...

The reason the switch cannot ping the RADIUS server is that the switch does not have an IP address configured on Vlan 1. If you configure the below on the switch, the switch can ping the RADIUS server:

interface Vlan1
ip address 192.168.1.4 255.255.255.0

I have attached the revised file (saved in PT version 8).

oh wow. this is a question to troubleshoot in my assessment and they have given me this network topology to work with and find the solution why they aren't pinging. That was exactly my issue, just pinging from the switch to the wireless routers via WAN addressing

[Georg Pauwen]

I am not sure if 'real' wireless routers have the same 'problem'. They do in Packet Tracer, and I am not really sure how they expect you to 'know' or 'conclude' that ICMP does not work with these devices in PT...

Either way, 'problem' solved !

another mystery to solve,

thanks for your help! greatly appreciated

Hello

So you have 6 rtrs in the same subnet all activley routing?

Can you post a topology diagram please

[Opaco95]

Hi Paul,

See topology below - routers WAN (internet) are all configured within the 192.168.1.0/24 subnet. Clients connected via wireless are in their own subnets off each router. Radius server is within the WAN subnet.

Hello

So are you using any IGP( rip/eigrp/ospf) or even just static routing for the wifi rtrs "own" subnets to be reachbale to each other?

[Opaco95]

hi paul

no routing has been configured because the LAN's dont need to reach eachother,

Only the switch needs to ping the WAN uplink on the routers
