PC in vlan unable to ping router

[Teoyucheng]

 

I have done the subinterfaces encapsulation on the router, done the switchport access vlan, switchport mode access

but i am not too sure where to put the switchport mode trunk and i am still unable to ping the router any help is appreciated

Your drawing shows information for r3 and r4. But shows only a single router. Is that significant?

If I interpret the drawing correctly the interface trunk should be FA0/1.

[Teoyucheng]

Im sorry but the R4 labeling is wrong it is supposed to be R3

[balaji.bandi]

You need to configure the Trunk port connected to the router.  (in your case as per the diagram fa 0/1)

still not working post the switch and router config ?

[Teoyucheng]

It has already been trunked to Fa0/1

Hello,

post the zipped Packet Tracer project (.pkt) file.

[balaji.bandi]

if you like to gigabit interface with subinterface 

interface GigabitEthernet0/1

no ip address 172.16.70.1 255.255.252.0

duplex auto

speed auto

no shutdown

create another subnet for VLAN 70 or 192.168.70.X  subnet

[Teoyucheng]

I removed the ip and it still didnt work

[Georg Pauwen]

Which PC (which IP address) cannot ping which IP address on the router ? You have put an IP address on the physical interface of the router, which means that this is the Vlan 1 IP address. Typically, your switches have an IP address in Vlan 1 as well.I have added the management IP addresses to the Vlan 1 interfaces of the three switches (see project file attached).

[Teoyucheng]

PC0 172.16.10.2  should be able to ping the 172.16.10.1 on the r4. I am still unable to ping with the file u sent

Hello,

the problem was that Vlan 10 did not exist on the switch connected to the router. I manually created the Vlan. All links between the switches and the router must be trunks. Working file attached.

[Richard Burts]

It sounds like @Georg Pauwen has got it. If problems persist please post the output of these commands on the switch

show vlan

show interface trunk

show interface status

[Teoyucheng]

The only issue right now is that PC0 and PC1 are in vlan 10 PC2,3,4 are in vlan 20 and when i switchport access vlan 20 the vlan 10 stops working

Edit/ Create vlan 10 and 20 on switch connected to router

[Teoyucheng]

It works now but can i ask whats the command to manually make the vlan?

Edit/ vlan (number)
