i have the wifi controller ip add 192.168.80.2 and this interface connected with fortigate firewall 192.168.80.1,

and i want to place the cisco router between these two interfaces.(cisco router's having two interfaces only)

in clear,

how to make my cisco router to act like a switch.?

did u understood my question?

[Masoud Pourshabanian]

Use these commands on that router

interface FastEthernet0/0
bridge-group 1
!
interface FastEthernet0/1
bridge-group 1
!

bridge 1 protocol ieee

Hope it helps,

Masoud

no, it's not working, any other soln.?

if you want to give IP to that router to be accessible by 192.168.10.X.

!
bridge irb
ip routing
!
!

interface FastEthernet0/0
bridge-group 1
!
interface FastEthernet1/0
 bridge-group 1
!
interface BVI1
 ip address 192.168.80.3 255.255.255.0
!
ip route 192.168.10.0 255.255.255.0 192.168.80.1


!
bridge 1 protocol ieee
bridge 1 route ip

Hello,

You said you want that router to be like a switch, but here you have configured routing. I am still not clear what you are doing.

If you want that router to be like a switch you need to disbable ip rouring.

interface FastEthernet0/0
bridge-group 1
!
interface FastEthernet0/1
bridge-group 1
!

bridge 1 protocol ieee

no ip routing

Gateway of WIFI router will be firewall which is 192.168.80.1

i am able to get the traffice from gigabit ethernet 0/1, but this 0/1 ethernet does not forward the traffic to gigabit ethernet 0/0 port... i dont know why?

[Masoud Pourshabanian]

Hello, 

you need to disable ip routing.

Config terminal

no ip routing.

The original poster has indicated that he wants to make this router work like a switch. I am not sure why he wants this but this is what he asks for and that is what we are trying to solve. One solution suggested was IRB. That should work but is a much more complex solution than is needed to satisfy the original request. Several people have suggested the solution of using bridging on both interfaces. But that is only part of the solution. The result of configuring bridge groups on both interfaces is that they will bridge non IP traffic. Masoud has correctly identified the issue that while IP routing is enabled that the interfaces will not bridge IP packets. The complete solution includes the bridge groups on both interfaces and turning off IP routing. +5 to Masoud.

Thank you Richad for the rating. The only thing I can think of is that the poster want to solve issues caused by the long distance between firewall and WIFI router with an available router.

Dear Sundar, 

So you have the ip natting configuration done on the router ? if so is the natting that was done is working ? kindly share more details and let us know what is your objective in placing the router between those 2 routers.
