[c-nsp] How to get VLAN from Switch to a Router via another switch

[David J. Hughes]

Does 3550-B even know about vlan 900?  Is there :

1. an access port in 900 on that switch
2. VTP running between the switches
3. a manually created entry in the vlan database

what does "show vlan id 900" on 3550-B say.
