Hello,
I am using GNS3 with microsoft loopback adapter and Cisco Configuration Professional 2.7. I can ping and run CCP when I add ip address on fa0/0. But when I create a subinterface on the router, I cannot ping and CCP shows discovery failed.
I created the following subinterfaces on router:
--------------------------------------------------------------------------
!
interface FastEthernet0/0
no ip address
duplex auto
speed auto
!
interface FastEthernet0/0.60
description Data VLAN
encapsulation dot1Q 60
ip address 10.60.0.1 255.255.255.0
!
interface FastEthernet0/0.61
description Management VLAN
encapsulation dot1Q 61
ip address 10.61.0.1 255.255.255.0
!
interface FastEthernet0/0.65
description Voice VLAN
encapsulation dot1Q 65
ip address 10.65.0.1 255.255.255.0
!
interface FastEthernet0/1
no ip address
shutdown
------------------------------------------------------
I also configure the Router for CCP access with following commands:
username student privilege 15 secret cisco
ip http server
ip http authentication local
line vty 0 15
login local
exit
ip http secure-server
line vty 0 15
transport input ssh telnet
end
-----------------------------------------------------------------
Microsoft loopback ip address is 10.60.0.5 255.255.255.0 and I tried to discover router in CCP with ip address 10.60.0.1
I am not sure what I am missing. Any suggestion?
Thanks.

Hi Arsen,
Discovery Details:
Discovering device 10.60.0.1
Connection to the device could not be established. Either the device is not reachable or the HTTP service is not enabled on the device.
I am trying to run ip address 10.60.0.1
From CMD, I can ping my loopback address (10.60.0.5) but I cannot ping the router's ip address 10.60.0.1
Thanks.

Hi,
Can you try this:
int f0/0.60
encapsulation dot1q 60 native
