I loaded today's daily build on RedHat EL 5.4 and
I am seeing some strange behavior with the route table
that is generated.
my ifcfg-ib0 script lools like this
DEVICE=ib0
BOOTPROTO=static
IPADDR=169.254.104.248
ONBOOT=yes
On OFED-1.5-rc2, the route table looks like this, which is what I expect.
[root at compute-0-7 woody]# netstat -r
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt Iface
192.168.25.0 * 255.255.255.0 U 0 0 0 eth0
169.254.0.0 * 255.255.0.0 U 0 0 0 ib0
default cst-head.local 0.0.0.0 UG 0 0 0 eth0
On today's daily build, the route table seems to be routing the IPoIB trafic
out eth0 instead of ib0.
[root at compute-0-7 woody]# ssh c0-6
