[openib-general] configuring ipoib

[Kanevsky, Arkady]

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.
