Telnet to multiple subnets

Hi everybody,

Can someone please help me what the best solution is to telnet to each switch/router whit a different subnet

I do not have solid routing/switching background.

I know how to telnet to one subnet ( 10.10.101.1 ) example i make a bridge to my networking connections and manually ad a ip adress that resides

in the same subnet

But i like to know how to telnet to a network whit 2 different subnets.

I'm adding a table to show you how the ip adressing scheme looks like.

Scenario.

I have a cisco voice home lab consist of the following:

1x2811

3x2801

1x3750

servers:

CUCM (Pub/Sub)

CUPS

CUC

CUCCX

Win2k3 AD

Any help will help

Thanks!

How to telnet to a cisco home lab whit different subnets

Hi Monasir81,

if you want to execute ping or telnet to a device in another subnet the switch must have a default gateway configured.

Now let’s see the configuration for a cisco switch.

Ip address

To configure the ip address first you have to enter from global configuration mode to interface vlan 1.

Switch#

Switch#conf t

Switch(config)#int vlan 1

Switch(config-if)#ip address {your ip address} {mask}

Switch(config-if)#no shutdown

Default Gateway

Be careful!!! The configuration of default gateway takes place in the configuration mode and the command does not include the mask for the ip.

Switch#

Switch#conf t

Switch(config)#ip default-gateway {ip address}

Now you can access your switch remotely, you can ping it from another network with different subnet and start “playing” with the settings. Have fun

Hope it helps.

Regards

Please rate if it helps.
