Configure VLAN on Cisco 881

[Andrew Duffield]

Hi

I have a customer who is on thr 192.168.254.x subnet and is using a Cisco 881 as their gateway.

They wish to create a second VLAN for the 192.168.253.x subnet.

The Cisco has Dialer0 configured for an ADSL connection.

I have partly configured the router but need some assistance regarding router a device on the 192.168.253.x subnet to the internet.

Please could someone help me to configure routing to the internet on the new VLAN and assist in setting up a DHCP server on that vlan.

I have attached a copy of the current config.

Thanks in advance

Andy

Hi,

no ip route 192.168.253.0 255.255.255.0 Dialer0

access-list 1 permit 192.168.253.0 0.0.0.255

ip dhcp excluded-address x.x.x.x x.x.x.x    This is range of ip address you want to exclude from pool

no ip dhcp conflict logging

ip dhcp pool 253pool

network 192.168.253.0 255.255.255.0

default-router 192.168.253.254

dns-servers x.x.x.x x.x.x.x     These are the DNS servers from ISP

Regards.

Hi Alain

Thanks for this.

In which order do I add the config?

Does the DHCP config need to be added separately?

I assume that a route isnt needed if the device is directly connected?

Cheers

Hi,

you can copy paste the commands I gave you in global configuration mode. If these devices need to go to Internet then they'll need a default gateway( either via DHCP like configured  with default-router command or via static config on the hosts)

Ok

How do I assign the DHCP pool to only issue IP's out of FastEthernet 2?

I am setting up a VLAN on their switch to segregate their current DHCP Server (Server 2008) from the one on VLAN 10.

Thanks

I don't understand what you mean by that ?  Can you explain further your topology

Hi Alain

I have an internal LAN of 192.168.254.x/24.

This has a 2008R2 server running DHCP.

They have 4 Wireless Access Points.

I want to create a separate VLAN for a guest wifi.

I want it on the 192.168.253.x/24 subnet.

The guest WAP will issue DHCP with the ip of VLAN10 as the gateway.

Does this make more sense?
