Can I bridge TWO (2) wireless cards on ONE (1) RouterBoard?

Hi there all.

Can someone please advice me IF I could have TWO Wireless cards on ONE routerboard (ex. RB433xx) and BRIDGE them together WITH the ether1 LAN to have N+1 config?
Two DIFFERENT frequencies will be used on these two wireless cards on one side of the link and the EXACT SAME config on the other side of the link.

Will it work as I want?
For example: IF ONE wireless link goes down (due to malfuction or something), will the SAME DATA pass through the other wireless link (through the other wireless cards)?

Thanks in advance.

I would not do bridging but instead do routing with ospf on these interfaces and configure mpls for the layer2 path (if needed).

To answer your question directly, you can bridge it all, but watch out for L2 loops.

Routing it all would be better.

Thanks for your replies guys. :slight_smile:

Actually I want to built a link as PtP Bridge with 2 x RB433xx routerboards and 4 x Wireless cards (2 on each of them).

To be MORE precise:
a. I need from SPOT A to pass a 107.113.0.xx IP to SPOT B transparent (the other end to see the EXACT SAME IP address 107.113.0.xx to “draw” the data sending from it).
b. I want safety and reliability, that’s why I need to put 2 x wireless cards on each routerboard.

QUESTION:

IF I have the below config:

IP input 107.113.xxx.xxx (from an outputing device) > IN to a SWITCHER > TWO outputs FROM the switcher “driving” TWO different STATION Bridges (2 x Wi-Fi) > go to TWO different AP Bridges (2 x Wi-Fi) > outputs into 2 ports of a switcher > SAME SWITCHER (5 ports) outputs 2 ports into TWO different STATION Bridges (2 x Wi-Fi) > go to TWO different AP Bridges (2 x Wi-Fi) > outputs into 2 ports of a switcher > CAN I get the IP 107.113.xxx.xxx from the last switcher?
IF ONE LINK goes down, WILL I be able to get the IP 107.113.xxx.xxx from the last switcher from one link?


Questions!.. :confused:

Anyone out there? :frowning:

You can either do this by having redundant links at layer 3 - (i.e. IP routing with OSPF determining the route actually used) or you could have redundant links operating at layer 2 provided that you have STP taking care of layer 2 loop avoidance.

If you are not familiar with layer 2, STP, ARP resolutions etc. then layer 3 may be more familiar territory.

Thanks CelticComms.

So it’ll be easier for me to use Layer 3 router right?
I’ve read that there are also Layer 3 switchers out there.
Will this do my work a lot “easier” for me (who I don’t know much about NETS) or it whould be the same as a L3 router?

Thanks M8.


EDIT:

Will such a solution work for me? http://wiki.ubnt.com/Mikrotik_bonding He says: “While the speedtest is running disconnect one of your ether’s connected to your UBNT gear, you should get a few missed pings then see something similar to the following.”
This means that IF one of them fails, the other one will continue to work outputing the data I want? Acctually I DON’T need high throughput - only ~ 10Mbps. I will use for EVERYTHING the RB411AH routerboards and a R5SHPn on each one of them.

The bonding approach would work and can make use of both links when both are working. If the wireless gear is Mikrotik at both ends you have a lot of different options (some layer 2 approaches do not work well across multiple vendors).

To bring clarity to the situation I suggest that you list and prioritize your goals and estimate a workable budget. That should at least let you decide on the appropriate purchases and get some testing experience before final deployment.

If I use the RB435G with 2 x Wi-Fi mini-pci cards in all my spots (3 of them), will I be able to do my job with this router without needing another (external) router?

I mean:

SPOT A (Start): Switcher goes to RB435G + 2 x R5SHPn
SPOT B (Middle): RB435G + 2 x R5SHPn out to a Switcher and goes to RB435G + 2 x R5SHPn
SPOT C (Other end): RB435G + 2 x R5SHPn out to a Switcher

Thanks in advance.

Not to start a new topic.

QUESTION:

What would you suggest for bondind options (NOT too much traffic - only 2 clients):

a. 2 x RB411AH with 1 x radio on each of them, connected to a RB750UP to bond them?
b. 1 x RB433AH or RB433GL with 2 x radios on it (internal routerboard bonding)?
c. 1 x RB435G with 2 x radion on it (internal routerboard bonding)?

Thanks.
