Why i cannot ping my switch IP address??? I am really upset and please help me.

Please check my simple diagram created using packet tracer over here:-

www.mediafire.com/?2mmimynyj4z

I have created two sub-interfaces with fa0/0.1 for vlan 1 (native) and fa0/0.2 for vlan 2

fa0/0.1 gateway IP: 10.10.10.1
fa0/0.2 gateway IP: 10.10.20.1

Only using 1 PC (IP: 10.10.20.2). Able to ping to 10.10.10.1 but cannot telnet or ping 10.10.10.2 from the PC. Already created vty password (cisco) and enable password (cisco).

Using ospf protocol.

Thanks

Hi there,
Didn't get the idea of creating sub interfaces on the switch itself. You normally creat a VLAN and then assign a range of interfaces from the switch to it. That creates the VLAN. Then you give a default IP address to that VLAN itself so that the PCs belonging to that VLAN are able to do management of that switch.
The sub interace that needs to be created is on the router interface with which the switch interacts. That's where you need to tell the router that it will be expecting data from x number of VLANs.

The default gateway of any switch needs to the IP address of the outer interface with which the switch interacts. That would help individual VLANs to be able to ping each other.

I checked your pkt file. You need to add a default gateway IP to the switch. Like this:

[code:1]Switch(config)# ip default-gateway 10.10.10.1 [/code:1]

This will tell the switch where to send traffic that doesn't belong to VLAN1. It worked fine after doing this.

You're welcome mate. Next time onwards, I'll try and be a little bit more straight-forward as solo.
