Level 1

Hi, I have a cisco 3825 router with two GE interfaces. GE0/0 is connected to a switch through ethernet cable. I have configured the GE0/0 interface with IP address. I have also configured static route for the local network. However, now I can only ping the GE0/0's own IP from the router. Here are the running-config:

hostname Router

!card type command needed for slot 2

end

The 10.1.52.1 is the current gateway on the 10.1.52.x LAN.

Can anyone please help here?

Thanks a lot!

OK. I will try to update the IOS. Do you think it has something to do with the version? Thanks.

My friend,

i believe that without encapsulation you will not communicate with your internal vlans.....

Good Luck

Alessio,

Thanks a lot. encapsulation solved the problem. I configured subinterface ge0/0.1, with ip address 10.1.52.4, and encapsulation dot1q 3, then I can ping gateway (vlan 3) and other hosts.
