Normally, in linux, you specify IP aliases thusly:
ifconfig <inferface>:<aliasnum> <ipaddr>
So to add a 2nd address to eth0, do this:
ifconfig eth0:1 1.2.3.4
And a 3rd like this:
ifconfig eth0:2 5.6.7.8
etc...
I would assume IPoIB interfaces behave the same way...
by the way, the <aliasnum> can be anything string.

Thanks guys.
Please, excuse my terminology.
No I can route a single IP address to an IB port.
But how do I route 2 (or more) IP addresses to the same IB port?
If I specify the same ib# it just changes an associated IP address for
the port.
If I specify next ib# it returns an error since that ib# does not have
a port behind it.

Nit: For linux, Christoph Hellwig (and others) have explained
that the ip address is associated with the host, NOT any
card. The route to the subnet is associated with the card.
