It's not clear on the documentation, but you have to at least configure
gated or some sort of routing alternative (like static routes).

VIPA is a virtual interface on your system .
To get benefice of VIPA, some physical interfaces must be configured too .
..
..
"Clients" systems access VIPA adress across one of above physical interfaces
(it depends of the routing configuration) .
If this interface fails, a new routing must be configured on client pointing
to
one of the remaining non-failing interface .This can be done using GATED ,
static route ...

Hope this help .

Let's say that you have 2 physical adapters, en0 and en1, 192.168.10.1
and 192.168.20.1 with a netmask of 255.255.255.0. And then you configure
a vipa address, vi0, 10.0.0.1/255.255.255.252 that you want to make high
available.

You will need to have something like the following gated.conf file:


----------------
routerid 10.0.0.1;

traceoptions "/var/adm/ras/gated.trace" replace size 1 m files 4 all;

rip no;
ospf yes {
area 0.0.0.1 {
interface 192.168.10.1 cost 2 {
retransmitinterval 5;
priority 0;
hellointerval 10;
routerdeadinterval 40;
};
interface 192.168.20.1 cost 2 {
retransmitinterval 5;
priority 0;
hellointerval 10;
routerdeadinterval 40;
};
interface 10.0.0.1 nonbroadcast cost 4 {
retransmitinterval 5;
priority 0;
hellointerval 10;
routerdeadinterval 40;
};
};
};

import proto ospfase {all;};
----------------


But for this to work on the other side there must be something that
understands ospf, like a cisco or an AIX box with gated configured. I
can help you with the AIX box configuration, but not with the router
configuration... is not my subject. Or you can use static routes on the
other side, but they need to be able to detect dead gateways.

Hope this helps!

THANKS! ...

but .. i have configured the gated like that ( with my IPs) and our
network uses ospf ... but it does not work!

so i have not to configure somethin on the (ospf) switch/router? ...

You do have to configure something on the switch, but on that, I can't
help you... a really don't know! The only thing that I know is that the
OSPF area must be the same.
The other way is that if you are using another AIX box, doing that
configuration it will work.
