VLAN Routing

Hi Solo,

Firewall is also disabled.

Here it is, I have managed to add a router and that is why I have 172.21.126.1 address on its interface (gateway).

VTP Server SW:

enable secret 5 $1$mERr$uRgsrGLy/wlQBBuvhG2YJ1
!
ip routing
!
ip ssh version 1
!
port-channel load-balance src-mac
spanning-tree mode rapid-pvst
!
interface Loopback0
ip address 192.168.1.2 255.255.255.0
!
interface FastEthernet0/1
switchport mode trunk
!
interface FastEthernet0/2
switchport mode trunk
!
interface FastEthernet0/3
!
......
!
interface Vlan1
ip address 172.21.0.253 255.255.255.0
!
interface Vlan3
ip address 172.21.8.253 255.255.255.0
!
interface Vlan6
ip address 172.21.128.253 255.255.254.0
!
interface Vlan7
ip address 172.21.130.253 255.255.254.0
!
interface Vlan9
ip address 172.21.126.253 255.255.254.0
!
ip classless
ip route 0.0.0.0 0.0.0.0 172.21.126.1
!

VTP client SW:
enable secret 5 $1$mERr$uRgsrGLy/wlQBBuvhG2YJ1
!
!
spanning-tree mode rapid-pvst
!
interface FastEthernet0/1
switchport mode trunk
!
interface FastEthernet0/2
switchport access vlan 7
switchport mode access
spanning-tree portfast
!
interface FastEthernet0/3
switchport access vlan 6
switchport mode access
spanning-tree portfast
!
interface FastEthernet0/4

Also I have noticed, what will be the gateway of my PCs that is in different VLANs? I have tried 172.21.128.1 for PC1 and 172.21.130.1 for PC2.

Maybe I'll change my Avatar to have my own distinction here.

Thanks a lot.

I'm not sure I get the full picture here since I don't know how things are connected, But if I guess. Your two PCs are connected to FastEthernet0/2 and FastEthernet0/3. If thats true, then the gateways should be set to the same IPs of VLAN6 (172.21.128.253) and VLAN7 (172.21.130.253).

For your extra router, I'm guessing it's connected to Vlan9 but I'm not sure to which physical interface. If you could describe your topology a little more it might help us help you.

Hi Solo,

It is now working, after I have defined the right gateway of PCs (*.253) and also after I remove the router. Now, I am troubleshooting the problem that when router is connected, the PCs did'nt see each other.

I'll let you all know once I figured this out. If you have any ideas, you are all welcome. Your inputs will be great help. Thanks.

Cheers!

I was just curious, was this VLAN created in a work environment or lab environment?

Hi Zippy,

I am working in a lab environment and once finalized and working I will apply it in Production.
