Please i need someone to explain to me on how to configure vlan in RB 750 and also how i can use RB750 to route the vlans.
i have done some configurations on the routerboard, i am only able to browse with only one subnet of IP address but the other ones i can browse with them.
attached is the RB750 export config i did on the board and also the config on the cisco 2950 switch for any one to look at and make corrections.
I would appreciate quick response.

The only things that stick out to me:
use-service-tag should be set to 'no', and while you can have a VLAN id of 1 in an 802.1q header Cisco treats VLAN 1 as native by default, and does not tag it. For this to work on the RouterOS side you'd have to enter the 'vlan dot1q tag native' global command, or change the native VLAN on the trunk to the router via "switchport trunk native vlan [x]", with x being a VLAN id that doesn't exist in your switch VLAN database.
You may want to remove 192.168.88.1, the default configuration IP address. Right now that IP is active on your VLAN 1 since as explained above VLAN 1 is coming in as untagged frames.
You have a static IP for the WAN, remove the DHCP client (this doesn't hurt anything, but isn't needed).
You can remove all but the first line, which in English means "when traffic leaves the router through the WAN interface, source NAT it to the primary IP address configured on that interface". The other rules are never used.
