IP MAY NOT BE CONFIGURED IN L2 LINKS

[razzakid]

Hi guys.Need your help!!!Got a router for a day cisco , and was tasked to connect the router through a router that is Magenta Router and Cisco Router. I also connected a switch which comes from cisco. Tried to configure cisco router , 2 interfaces.INSIDE - OUTSIDE. When I try to configure INSIDE routing does not work. Writes Ip may not to be configured in L2 links.When I do it through a Vlan that is configured on the inside Routing in Vlan then works but can not go to Cisco router and also can ping Magenta router although in VLAN they are in different networks.What to do? My task from work is as follows:
1)Connect everything and configure 3 networks.
2)1 Network PC PHONE WIFI
3)2 WIFI NETWORK Work
4)3 WIFI network Guests

Help me please how to do it?
For example :
1) network 192.168.1.2 255.255.255.0
2) network 192.168.2.2 255.255.255.192
3)network 192.168.3.2 255.255.255.252

3 Networks should be on the Cisco Router.The Magenta Router is just WAN

You need to provide diagram how these connected.

Router--Switch--Devices ?

Then you need to configure Router in stick and NAT configuration to work.

Can you post show run from Switch and Router to understand.

Based on the drawing what I would expect to see on your 1941 router would be a routed (layer 3) interface connecting to the WAN router and a routed (layer 3) interface with subinterfaces for 3 vlan connections connected to the switch. But the partial configs that I can see are quite different. They suggest that your 1941 has an Etherswitch module and that the connection from 1941 to the switch is on one of those ports. In that case what needs to be configured is that the router interface connecting to the switch is configured as a trunk and then to have vlan interfaces on the router for the 3 vlans/subnets on the switch. Also to have the switch interface connecting to the router to be configured as a trunk.

you mention subnets that differ to the topology being shown?
Below is based on the topology.

Hello,

is this actually a 1941 router you have (or have you just used this is an example in Packet Tracer) ? The easiest way to figure this out is for you to post the output of 'sh run' from both the router and the switch. Put the output in a text file, and post both text files here...

how do i copy the show run cfg?YEs that is my router that i have

[Georg Pauwen]

Hello,

you are connected to the router with a console cable, or any other access to the command line ? Just issue the 'sh run' command, select the entire output and copy it to text file (using e.g. Notepad).

i am in command line , when i press ctrl c to copy that , he is going out from config mode....with mouse the same.I am on ubuntu system

[Georg Pauwen]

Hello,

what if you just TFTP the running config from flash to a TFTP server ?
