Does your trunk port have to be in the same vlan in order to....

[pctechnician]

running a 24 port cisco 2950 which is directly connected to a 2600 router.the router ip address is 10.10.21.1 ports 1-4 are associated w/ VLAN10 which ip is 10.10.21.1
ports 5-7 w/ VLAN11 which ip is 10.10.21.2 I set port 8 to be the trunking port for both of the VLANS. I put a test pc on vlan 10 to see if it can ping the router. didn't ping. then i put port 8 inside vlan 10 and pinged the router successfully.

I know its a trunking issue, but i cant figure it out.

basically i want to know if i can set port 8 to be the trunking port for two different vlans.

Double check your IP addressing. Try using 10.10.21.1 (router) and 10.10.21.2 (pc) with subnet mask 255.255.255.0 on vlan10 and 10.10.22.1 (router) 10.10.22.2 (pc) mask 255.255.255.0 on vlan11.

Vlans are logically seperate networks with different address space. It appears as if you were using the same subnet for both vlans.

Couldn't have said it better. Your subnets are the same even if you were using a /30 mask. So you need to change your addressing. Why don't you use 10.10.21.x and 10.10.22.x with a /24 mask and you should be ok.
