I have a lab consisting of 3 segments;
Segment 1: R1 with 2 swithces: 5 VLANS, ports trunked with dot1q, vtp was configured, sub-interfaces have been configured with different subnets for each VLAN, and everything is working just fine.
Segment 2 and 3: uplink ports and interswitching ports have been trunked with dot1q, vtp domain has been set; however, the VLANs from segment 1 aren't traversing to segment 2 or 3. What am I missing here?
Thanks,

From what I gather from your post, you are trying to propogate VLANs across a router (R1). It is not possible to route VLANs - the only way to do this is to bridge the interfaces on the router using IRB. Here's a good link on this:
