Dear members.

I have some question about Infiniband Partitions.

I would like to build Linux box with IPoIB Router.

* Questions

 My Question is the following.

 a) Can I create the following IPoIB network ??

 b) If so, how to setup /etc/opensm/partitions.conf??

* Problem.

 Ping IB Client to Router : I got the followig error.

 Network is unreachable.

* Environment

 OFED: OFED-1.5.3.2
 OS:   Scientific Linux 6.1

* Linux box (Router)

 1 ethernet interface  (eth0)
 1 Infiniband interfae (ib0)
 Run subnet manager.

* Ethernet setup

 a) add VLAN ID 120 eth0.120 (192.168.120.0/24)
 b) add VLAN ID 130 eth0.130 (192.168.130.0/24)

* Infiniband Setup

 b) add subinterface 1 ib0.8001 (192.168.1.0/24)
 c) Run opensm


 I crated subinterface with the following command.

 echo 0 > /sys/class/net/ib0/create_child
 echo 1 > /sys/class/net/ib0/create_child
 and assign ip address with ifconfig
