Does any one know of a “how to” or recent docs on getting EoIP to work. the how to http://www.mikrotik.com/Documentation/HowTo.html#How_bridge is obviosly for a much older version because most of the commands don’t work. I have two RB532’s that I want to use to transparrently bridge a network segment using a wireless link. so far I havn’t found enough documentation to even get me started - any assitance would be much appreciated.
I set both units up with an EoIP tunnel (making sure mac addresses were different and tunnel id’s were the same) between the two wireless cards and then bridged the eth to wlan at each end - no luck
Next I tried putting the EoIP tunnel right from eth to eth interface - still won’t pass anything data that isn’t on the interface subnet.
Thanks for the link Christian - I had WDS & Bridges all set up and working. Unfortunately it doesn’t appear to pass all multicast packets and has issues with igmp that i don’t appear to be able to resolve. EoIP is my last resort at this point, I just don’t understand what needs to happen to make it all work
Your description of your first EoIP tunnel try reads good - create EoIP interfaces with the ip address of the adjacent wireless interface as then “remote-address”. Then bridge The EoIP interface on each system with the ethernet interface, and you should be set.
Things to watch out for:
Give the EoIP interfaces different MAC addresses (you wrote you did), like from the range starting with 00:00:5E:80:xx:xx.
Ensure you have the same tunnel-id.
Test your plain ip connectivity between your wireless interface ip addresses before setting up/testing the EoIP tunnels. Because there’s no real indicator if an EoIP tunnel is running correctly (i.e. it will show as running also when the remote ip address is not reachable etc., IIRC).
If that doesn’t work, check the bridge firewall (do you drop something there?).
If still a no-go, you will have to post some config snippets…
Hi Christian - because one of the routers I need to configure is at the top of an 80M tower (and i REALLY don’t want to have to climb up there with a console cable if I break it), I have been using two RB532’s on the bench with an ethernet cable between ether2 on each unit.
yes there is ip (and mac) connectivity between both ether2 ports
ether 1 on each unit has an address on a different subnet from each other and different from the ether2 ports network. there is even static routes so each ether1 network knows where the other ether1 network is
The configuration you described was as I had it (I think). Just to make sure I deleted all bridges and tunnels and started again.
I changed the EoIP mac addresses (left them as default on the last setup), to within the proper range
I added a new network address to each eather1 port (there are no static routes to this network on either RB532. with a 2 PC’s one plugged each into the ether1 ports of the RB532’s I can ping both RB532’s but not the PC at the other end. This is the same from each PC.
If I change the two PC’s onto a network that does not have an ip address on ether1 of the RB532’s they do not either.
If your worried about losing router connectivity when changing configuration, you could use safe mode. Just hit CTRL-X at a ssh or winbox console, then make your changes. If you lock your self out, then the router rewinds all the changes you made. I think it remembers around 100 changes.
Also, if you lock yourself out, MAC telnet is your best friend. It almost always works unless you totally disable an interface.
