Equal Cost Multipath Routing and Policy Routing

Sun Aug 14, 2005 3:50 pm

Hi All,

I would be interesting to hear from anyone who has got either of these going. I have had no success with either after very carefully following the guidance in the documentation.

Is it broken in the beta?? (I am using rc5 at present)

upgrade to 2.9rc10.
Than if something does not work, explain more detailed what exactly is wrong.

Hi Kipel,

OK, so I have upgraded to rc10, but the symptoms are the same. The set up here is a small cat5 newtwork with about 25 hot spot users, with two adsl connections on separate ethernet interfaces. Here is what I have done.

1. I checked that using both gateways separately that when a client uses http://www.whats is my ip.com the web site reports the correct ip number depending which gateway is enabled. When switching over gateways (disabling/enabling them in WinBox) I notice that sometimes the 'interface column' in Win Box shows "unknown". But its OK after a reboot.

2. I add both gateways as per the Equal Cost Multipath Routing routing example in the documentation. No matter what I do, traceroute from the MT box, or trace root from a cleint, I NEVER get the 2nd gateway, even after a reboot. Also when I look at the traffic graphs for each interface, the 1st gateway ALWAYS has much more traffic on it than the 2nd one.

3. So I try policy routing. I add the mangle rule in as per the example, using destination port=80, and routing mark as "adsl2". I set the routing-mark of the 2nd interface as "adsl2", but still http://www.whatsmyip.com ALWAYS reports the same IP number (of the 1st gateway, even after reboots).

4. I try pinging one of our servers (on a different site using its public ip address). I set the mangle rule to ICMP (no port number), but still a traceroute from the cleint computer still shows the old (1st) gateway, or times out. If I try pinging the remote server, I get a time out.

My question is, am I doing something wrong, or is this functionality in 2.9 rc10 broken??

Any advice gratefully received.
