Routing ma'm how i can create subinterface on router for intervaln and what is the command for creating subinterface on 2500series router

bridge irb
!
interface Dot11Radio0
no ip address
!
broadcast-key vlan 1 change 45
!
!
encryption vlan 1 mode ciphers tkip
!
ssid cisco
vlan 1
authentication open
wpa-psk ascii 0 cisco123
authentication key-management wpa
!
ssid ciscowep
vlan 2
authentication open
!
ssid ciscowpa
vlan 3
authentication open
Step 5 bridge-group number
Example:
Router(config-subif)# bridge-group 1
Router(config-subif)#

Assigns a bridge group to the subinterface.
Note When the bridge-group command is
enabled, the following commands are
automatically enabled, and cannot be
disabled. If you disable these commands
you may experience an interruption in
wireless device communication.

bridge-group 1
subscriber-loop-control
bridge-group 1 spanning-disabled
bridge-group 1
block-unknown-source

when you do the ip dhcp pool command, you need to give the pool a name, so the full command would be:
ip dhcp pool mydhcp

after that you would need to configure the network that you want to cover, and the default router that you would like them to use for the gateway.

Hope that this helps!

Its like router on stick configuration??enter the interface which you have to configure and in that interface as mentioned below
Hostname(config)#interface FastEthernet0/1
Hostname(config-if)#no ip address
Hostname(config-if)#no shutdown
Hostname(config)#interface FastEthernet0/1.1
Hostname(config-if)#encapsulation dot1Q 1 native
Hostname(config-if)#ip address x.x.y.y < subnet mask >
interface FastEthernet0/1.2
Hostname(config-if)#encapsulation dot1Q 2
Hostname(config-if)#ip address x.x.y.y < subnet mask >

You have to create a route statement to allow workstations to get online.

Below is the command:
route interface_name ip_address netmask gateway_ip

Example:
route outside 0.0.0.0 0.0.0.0 200.200.200.1
or
route outside 0 0 200.200.200.1

When there is already a route statement but still cannot get online, check the DNS settings.

connect with console and go to the interface.
put
access-list (any no like 101 etc) deny ip (source ip / ips) (destination)

You would need to trunk the VLANS to the router and create sub
interfaces and then, create access lists applied to
the interfaces to control inter vlan communication. I hope this helps,

Router interfaces something like this, may not work on all versions of
IOS:

interface FastEthernet0/0
no ip address
speed 100
full-duplex
!
interface FastEthernet0/0.1
description VLAN1_Servers
encapsulation dot1Q 1 native
ip address 192.168.1.1 255.255.255.0
!
interface FastEthernet0/0.2
description VLAN2_QA
encapsulation dot1Q 2
ip address 192.168.2.1 255.255.255.0
!
interface FastEthernet0/0.3
description VLAN3_DEV
encapsulation dot1Q 3
ip address 192.168.3.1 255.255.255.0
!
interface FastEthernet0/0.4
description VLAN4_FIN
encapsulation dot1Q 4
ip address 192.168.4.1 255.255.255.0

Type the code in the search bar(not search engine) try creating a password,you can put one in system settings and when you are prompted for a pword leave it out if you have'nt got one.Then under the wireless menu select Security.Choose a type of security you would like to use from the drop down menu(best one's are 64-bit and 128-bit)create a pass-phrase from there to create a word for you to remember and if needed copy the key.Finally reboot you router under the utilities section.

i can't set ip address over 4 vlans. the 3com switch 4500 always give error message "there's not enough routing resources available".please help....

go into router settings and change your wireless settings from wpa psk to wep (wired equivalent privacy) create a pass key and then type that into the box when prompted on your ps3 to access my router i need to have ethernet cable connected to pc and open ie browser page type 192.168.0.1 user admin password is password check under the router for your specific info
