Cisco 877 trun 2 vlan

[facundoo23]

I need to connect 2 vlan on a Cisco router VLAN 877 and the second does not connect to anything. PING only to itself, being one who hangs on a switch where there is another router with an IP in the range of VLAN 2. VLAN 1 works well.

interface FastEthernet0

interface FastEthernet1

switchport access vlan 2

!

interface FastEthernet2

!

interface FastEthernet3

!

interface Vlan1

Hello Facundo Cesar.

Regarding to the problem description, I was wondering about the configuration on the Switch interface connected to the Cisco877 Fa1...Could you please post the interface configuration of the connected switch ? Is it a trunk ?

As you can ping internally I suppose the VLAN 2 interface status is up/up

In fact I am thinking it could maybe be due to a STP port type  mismatch between Fa1 of the Cisco877 and the connected switch interface...I have been facing this issue in the past.

What is the output of  Cisco877# show spanning-tree interface FastEthernet 1 ?

If it is something like => Port 2 (FastEthernet1) of VLAN2 is broken (Port Type Mismatch) this is the issue.

If not we will have to continue the investigations :-(

Kind regards :-)

What may be happening is you have to build a trunking on Switch 2960 which hangs 877. But in 1710 I have no problem.

Hi,

Do you have a L2 VLAN created on your 877?

Router(config)#vlan 2

Kindly post your running config, show vlan-switch brief and show ip interface brief output.
