question about router vlan

[dannan lin]

hi:

i have a question about vlan setting in a router.

the following commands creat a vlan in a router but i do not know how and when to use it?

Router#vlan database

% Warning: It is recommended to configure VLAN from config mode,

  as VLAN database mode is being deprecated. Please consult user

  documentation for configuring VTP/VLAN in config mode.

Router(vlan)#

Router(vlan)#vlan 30 name v30

once i have created vlan on a router  i couldn't assign interface to that vlan like what we usually do on a switch. so what 's the purpose of router vlan?is there any simple experiment i can do ?

thanks in advance.

Do you have the NM16-SW module installed in the router?

[dannan lin]

no, i don't have real cisco router ro play with, i just do my test on simulation softwares(i.e. packet tracer). thanks for your reply.

Hi,

this kind of setup is done when you have a switch module in your router.

Hi,

you could do what you do with a L2/L3 switch but with less advanced features available.You would have to look at the doc for the particular switch module/ router pair and IOS.
