vtp client failing to update

[spfister336]

What would be the main reason for vtp client failing to update? It has the right domain name and a lower revision number. The server mode switch is directly connected. The client side, a 3640 router, has just an ip address, and the server side, a 3550 switch is set to mode dynamic desirable. Why might be the problem?

is the trunk up ?

Yes, it is. Up to this point, none of the vlans from that site have ever been needed elsewhere, but I'm on a project now to change that. Ip connectivity has been fine, but now I need it to pass vlan info.

Unless the 3640 router has a switch module installed and the connection from the 3640 to the 3550 is setup as trunk it does not use vtp .Normally a trunk between a router and a switch is forced on thus does not use vtp .

So is there any way to pass vlan informatin through this router?

Hi

No as the layer 2 broadacst domains are not allowed to span from the layer 3 devices.

Thanks
