Dear,

I have confused that how to route inter-vlan traffic forward  to internet?  ISP cable connect to port 48. and live ip for example 1.1.1.1

Can you guide me ?

Thanks.

Hi Junaid,

Assalamu Alikum,

To enable Inter VLAN routing on the switch by using the “ip routing” command.

then enable static routing on your core switch 

for example :

switch(config)#ip route 0.0.0.0 0.0.0.0 1.1.1.1

switch(config)#ip default-gateway 1.1.1.1

(1.1.1.1 is a next hop address of core switch connected towards ISP router) 

You can also enable routing by using port no

switch(config)#ip route 0.0.0.0 0.0.0.0 fa0/0

Hi Junaid,

please execute the following commands in your core switch

coreswitch:

----------

coreswitch(config)#ip route 0.0.0.0 0.0.0.0 121.121.121.212

coreswitch(config)#ip default-gateway 121.121.121.212

Please Find the Attachment

Note : Please Let me know is there any other devices connected between coreswitch and ISP
