James, can I see the switch config? vlan99 10.1.1.2 svi is going to be in vlan 99 10.1.1.1 on your router is going to be in vlan 120 don't you want these to be in the same vlan and same subnet? thanks, Nick

I have fa0/0 which has a configuration of: interface FastEthernet0/0 no ip address duplex auto speed auto ! interface FastEthernet0/0.77 encapsulation dot1Q 77 ip address 20.1.1.1 255.255.255.0 ! interface FastEthernet0/0.120 encapsulation dot1Q 120 ip address 10.1.1.1 255.255.255.0 ---------------- Router(config)#do sh ip int br Interface IP-Address OK? Method Status Protocol FastEthernet0/0 unassigned YES TFTP up up FastEthernet0/0.77 20.1.1.1 YES NVRAM up up FastEthernet0/0.120 10.1.1.1 YES manual up up As you can see on the output everything is running fine, interfaces are up. Now on the fa0/0.120 (10.1.1.1) it is connected to a switch f0/1. on the switch also it is configured with vlan 99 with ip address of 10.1.1.2 when I try to ping from router to switch using the fa0/0.120 (10.1.1.1) the output is down. but when I configure the ip address 10.1.1.1 of the router into the f0/0 interface (not the sub-interface) the ping is successful. Any advice? _______________________________________________ For more information regarding industry leading CCIE Lab training, please visit http://www.ipexpert.com/ Are you a CCNP or CCIE and looking for a job?
