Can Router pass traffic for this network

[mahesh18]

Hi Everyone,

Here is setup below.

Cisco Router has only 2 physical interfaces.

interface FastEthernet0/0  IP 10.220.35.20

interface FastEthernet0/1  IP 140.25.x.x

Where Devices 10.220.35.18 and 10.220.35.19 are switches and both have default gateway set to  10.220.35.20.

Where Switch 10.220.35.19 connects to Wireless device with IP 192.168.150.2.

I need to know if Router 2811 has no physical interface with IP 192.168.150.x  will it pass the traffic for AP and SM Subnet 192.168.150.x?

Regards

MAhesh

Hi,

May i know the switch interface which is connecting to AP and the running config of the interface?

You need to create a static route entry as below. However, you need to have some L3 link between AP and switch.

eg:

ip route 192.168.150.x 255.255.255.x 10.220.35.20

Switch interface 1/5 will connect to AP as trunk port carrying vlans 

say vlan 10  10.220.35.x

say vlan 30 192.168.150.x

These are non cisco switches.

So on both switches if i create static route

ip route 192.168.150.x 255.255.255.x 10.220.35.20  will it work?

Hi,

No need to add it in switches. You need to add the route in cisco router.

Small change in command : ip route 192.168.150.x 255.255.255.x 10.220.35.19"

Also make sure that the AP should have default route pointing to switch 192.168.150.X ip for reverse route.

Eg:

Cisco router will check the routing table to forward the traffic to AP ip address. Since you configure static route. The traffic will be forwarded to switch (10.220.35.19). Then that switch will check the local routing table and forward the traffic to AP with the help of vlan 30 ip address.

Also  the reply traffic comes vise versa.
