pinging switch from router and from router to switch.

[zakiullah27hassan]

hello, 

i have configured the port Ethernet0/0.10 on the router with the (192.168.10.1 255.255.255.0) ip address which i call vlan 10. The same way i have configured trunking and ip default-gateway on the switch. i cannot make the two devices ping each other. 

here is the summary of my routers configuration: 

interface Ethernet0/0
ip address 10.0.1.2 255.255.255.252
duplex auto
!
interface Ethernet0/0.10
encapsulation dot1Q 10
ip address 192.168.10.1 255.255.255.0

interface Serial6/0
ip address 10.0.0.1 255.255.255.252
serial restart-delay 0

router ospf 1
network 10.0.0.0 0.0.0.3 area 0
network 192.168.10.0 0.0.0.255 area 0

Here is my Switches configuration: 

interface Ethernet0/0
switchport trunk encapsulation dot1q
switchport mode trunk
!
interface Ethernet0/1
switchport access vlan 10
switchport mode access
switchport nonegotiate
!
interface Ethernet0/2
switchport access vlan 10
switchport mode access
!
interface Ethernet0/3
switchport access vlan 10
switchport mode access

interface Vlan10
ip address 192.168.10.10 255.255.255.0
shutdown

ip default-gateway 192.168.10.1

AS @MHM Cisco World mentioned please do Ping <SW vlan IP> source <subinterface IP>

[MHM Cisco World]

Since you use IP for main and subinterface then you need to use source in ping 

Ping <SW vlan IP> source <subinterface IP>

I have not given an IP address to my VLAN. Is it necessary to assign an IP address to the VLAN?

[MHM Cisco World]

You try ping from R to SW 

The SW have vlan 10 IP

"" interface Vlan10
ip address 192.168.10.10 255.255.255.0
shutdown""
