RDMA network Unreachable

[bin tang]

Hi, 

I'm using the RDMA environment, and before, I only needed to configure the ib0 IP address on both nodes. Now, this doesn't work.

I did it like this.

cp1.

sudo modprobe ib_ipoib

sudo ifconfig ib0 192.168.0.211/24

cp2.

sudo modprobe ib_ipoib

sudo ifconfig ib0 192.168.0.212/24

on cp2.

ping 192.168.0.211

result.

PING 192.168.0.211 (192.168.0.211) 56(84) bytes of data.

From 192.168.0.212 icmp_seq=1 Destination Host Unreachable

From 192.168.0.212 icmp_seq=2 Destination Host Unreachable

From 192.168.0.212 icmp_seq=3 Destination Host Unreachable

From 192.168.0.212 icmp_seq=3 Destination Host Unreachable

How should I configure the RDMA environment now? Is it updated?
