Hi,
I'm trying to communicate 2VLAN's in a 2900XL to a 2600Router. My 2600 supports dot1q so I changed the encapsulation and set 2 sub-interfaces on Eth0/0. However, seems there no comm. between 2hosts on the diff. subnets (e/vlan)I've configured both VLANs and set the trunk on Fa0/16 which is part of both VLANs 1 and 3. Any clues on this?
Thank you.

Configure the Link between the two swithces as Trunk link.i.e
switchport mode trunk
and see tht u dnot enable portfast on the ports used for trunking.

Probably have to post both configs . Also what model is the 2924 ? A old 4 meg or newer 8 meg model . The older ones didn't support trunking i don't believe .

Hi Rodrigo,
Instead of using multi vlan command on siwtch interface can you try this command
interface FastEthernet0/16
switchport trunk encapsulation dot1q
switchport mode trunk

The problem is your trunk port on the 2900, you have it configured as a multi-vlan port, not a trunk port. Remove the multi commands and set the port as a trunk. Your config should look like this:
int fa0/16
switchport trunk encapsulation dot1q
switchport mode trunk
!

Hi,
Im following the same configuration but now I added another sw2926-XL. The problem is: I cannot get to comm. I've connected a crossover between the 2 sw. (Fa0/17) STP is working in FWD mode in both interfaces. However, when I ping the router says Request Time Out. I've also put Fa0/16 which is the host on VLAN 02.
Please, can you help?

Hi,
I am trying to comm.3 routers on a hub-and-spoke topology. The HUB router comms.with the "left" router on a point-to-point connection fine. However, the int.S1(multipoint)connected to router "right" does not comm. Please, find attached 3conf.files of each router.
I hope you can see what is missing in my config.
Thanks.

Please, can you help?
