Dear All,
i am connected two routers with one switch.
SwitchA
interface FastEthernet1/0/1
Des Uplink to Switch B
switchport trunk encapsulation dot1q
switchport mode trunk
interface FastEthernet1/0/13
Des Rauter A
switchport trunk encapsulation dot1q
switchport mode trunk
!
interface FastEthernet1/0/14
Des Router B
switchport trunk encapsulation dot1q
switchport mode trunk
Router A
interface FastEthernet0/1.131
description Switch A port 13
encapsulation dot1Q 131
Router B
interface FastEthernet0/1.130
description Switch A port 14
encapsulation dot1Q 130
when i connecte router to switch i get this error.

Hi,
Are both routers connected to the same switch?
If yes, you need to put each port in a different vlan
for example:
you need to create vlan 130 on the port that is connected to router-B and 131 to router-A
Can you post sh run from the switch?

Hi,
Are ports 1/0/13 and 14 in different vlans?
have you created vlan 130 and 131 on the switch.
config t
vlan 130
config t
vlan 131
BTW, what you posted is not a full "sh run"

hi raza,
sorry i did not put full sh run
i have created VLANs on switch,

Can you past o/p of "sh vlan" from the switch?
Sh run does not show vlan 130 and 131. All it shows vlans 121&122.
08-30-2012 01:03 PM
Hi there,
Enable
vlan data
Vtp mode trans
Vlan 131 name myvlan131
Vlan 130 name myvlan130
Apply
Exit
Conf t
Int vlan 130 ! This way you create the svi, not the vlan
Ip address 130.130.130.1 255.255.255.0
Int vlan 131
Ip address 131.131.131.1 255.255.255.0
!
End
Wr

Hope this helps

You have two options.
Remove the trunk config from the interfaces on the switch and the subinterfaces from the router since there is only one VLAN and the trunks are not really needed when there is only 1 VLAN.
Or
Configure the native VLAN on the switch ports.
Int f1/0/13
Switchport trunk native vlan 13
!
Int f1/0/14
Switchport trunk native vlan 14
!
Hope this helps

hi Tglen
thanks for reply
i need to add some more subinterface, but this problem i can do.
i have tried your suggestion but didnot work.
regards
08-29-2012 05:35 PM
can you post a diagram of your network?
08-30-2012 02:04 AM
Hi
I see You have configured native vlan on the switchports going to the routers. Have You configured those vlans as native (untagged) on the routers? If not, I suggest that You configure the same native vlan on the router that is configured on the switchport.
