Hi Guys, I have a 2811 router and 3560 switch. I would like to set up router on the stick. Here are the configs of 2811 and 3560. I have an IP phone on the 192 vlan which I can ping from the router, but I can't ping it from the switch nor from the headquaters (thru serial). I have the same set up at another location just using 2600 router and everything works fine. Thanks.
Configuration on the router: (Partial)
! interface FastEthernet0/0 description $ETH-LAN$$ETH-SW-LAUNCH$$INTF-INFO-FE 0/0$ no ip address duplex auto speed auto ! interface FastEthernet0/0.1 encapsulation dot1Q 1 native ip address 10.21.64.254 255.255.255.0 ip helper-address 10.21.56.103 no snmp trap link-status ! interface FastEthernet0/0.192 encapsulation dot1Q 192 ip address 192.168.124.254 255.255.255.0 ip helper-address 10.21.56.103 no snmp trap link-status ! interface FastEthernet0/1 ip address 10.21.80.254 255.255.255.0 duplex full speed 100
