can not ping some loopback interfaces

njconnect
Level 1
Level 1

I am using packet tracer to prepare for my CCNA exam

I created the following network environment

 

I have (2) 3560 multilayer switches.  I have created a port channel trunk interconnecting the 2 switches using ports Gi0/1 - Gi0/2.

I created 2 VLAN and assigned them ip address

VLAN 2: ip address 192.168.2.1/24

VLAN 3: ip address 192.168.3.1/24

On Switch 1 I've created interface Loopback 0 with ip address 10.0.0.1 255.255.255.255

On Switch 2 I've created interface Loopback 0 with ip address 10.0.0.2 255.255.255.255

I've enabled IP routing on both switches

i Have one server connected to port fa0/2 which is vlan 2.  I can ping both 

VLAN and pcs in those vlan as well as the loopback interface of Switch1 from the switches and computers.  I can not ping the switch2 loopback interface from Switch one or any of the computers.

 

I don't understand why.  Essentially what i would like to be able to do is assign each switch a loopback interface that i can ping from the all the computers.

 

I've included the config for both switches below.  I've also included paketTracer file.  switch logon is username superman password krypton

Hello,

 

the easiest way would probably be to run RIP on both switches:

 

router rip

version 2

network 0.0.0.0

 

Can you give that a try ? Otherwise, post the Packet Tracer project file (zip it first before uploading)...

I've gone ahead and added the packettracer file.  switch username superman password krypton

 

Hello,

 

what are your requirements ? Since both 3560 switches are L3 switches, and you have IP Routing enabled, you need to configure the default gateway for each PC on the directly connected switch. I can completely rebuild your network to get it to work, but what requirements is this based on ?

I've disabled ip routing on Switch2 and set the default-gateway 192.168.2.1 as per your suggestion. 

 

The basic requirements are

1. 2 switches interconnected with a trunk port 

2. at least 2 vlans configured 

3. vtp enabled

4. loopback interface on each switch should be reachable from computers or other devices.

5.  I should be able to ping all computers, vlans and loopback interfaces

The packet tracer file has already been uploaded in the original post
