Let all leafs have a link block to all the hubs you want, don't make them auto-connect.

Make link blocks to the leafs on your hubs, make them auto-connect. When 1 hub fails, the leafs will also disconnect, and one of the hubs will auto-connect to the leafs.

(Thats how we do it, can't think of another way.)

Can you give me an example of your ircd.conf?

Config on a leaf:

Code: Select all

link                    hub.number.one
 {
        username        *;
        hostname        12.34.56.78;
        bind-ip         *;
        port            7001;
        leaf             *;
        password-connect "pass";
        password-receive "pass";
        class           servers;
 };

link                    hub.number.two
{
        username        *;
        hostname        87.65.43.21;
        bind-ip         *;
        port            7001;
        leaf             *;
        password-connect "pass";
        password-receive "pass";
        class           servers;
};

Config on hub 1:

Code: Select all

link                    leaf.one
 {
        username        *;
        hostname        12.34.56.78;
        bind-ip         *;
        port            7001;
        hub             *;
        password-connect "pass";
        password-receive "pass";
        class           servers;
        options {
              autoconnect;
        };
 };

Config on hub 2:

Code: Select all

link                    leaf.one
{
        username        *;
        hostname        12.34.56.78;
        bind-ip         *;
        port            7001;
        hub             *;
        password-connect "pass";
        password-receive "pass";
        class           servers;
        options {
                autoconnect;
        };
};

And of course the 2 hubs should be linked too

Say, leaf 1 is linked to hub 1, hub 1 is linked to hub 2

hub 1 -- hub 2
|
|
leaf 1

Now hub 1 fails, so hub 2 looses hub1 and leaf1. Because of hub2 having the autoconnect option to leaf1, it will try to link to leaf1

hub 2
|
|
leaf 1

And as soon as hub1 comes back, hub2 links to hub1, and leaf1 will still be linked to hub2 (until hub2 fails)

-edit-
Of course you can also make the leafs use autoconnect! Don't know for sure why we let the hubs use autoconnect, gets rather annoying if a server drops out for some time.
