We are running 2 2950s connected via Aironet 1410 wireless bridges.
We have had to implement multiple vlans on the remote site and have run in to problems with vtp not running across the link.
We added the new vlans to the bridges, trunked the 2950 ports on which they are connected and vlan tagged packets are traversing the link as expected. Unfortunately if a vlan change occurs on the main network, the vtp update does not get propogated to the remote 2950.
To make matters more frustrating we have another separate Aironet 1410 wireless link running to a different site (but with a 2924 at the remote end) and vtp updates are getting through. Yet we can't see any discrepencies in either switch or bridge configs which is causing the lack of vtp updates to the second wireless network.
Here is an excerpt from the local bridge's config showing the 3 vlans running across the link.

It isnt a major problem as the vlan data is getting through and users are able to logon to the network regardless of the vlan they are connected to, but it is an annoying glitch I would like to rectify. Does anyone have any suggestions on how to fix this problem?
