[Lustre-discuss] Help with lustre routing

[Eric Adint]

OK i have read the manual and i have read the boards and done as much  
research as i can, but i cant seem to bend my head around this, what i  
want to do is create a router so that i can keep my OST and MGS/MDT on  
the IB network and have another computer handle the ib to ip routing.
here is the configuration.

nas-0-0,  MGS/MDT , OST1 - o2ib 192.168.1.2, tcp0 10.1.254.3
nas-0-1, OST2   		- o2ib 192.168.1.3, tcp0 10.1.254.4
nas-0-2, OST3   		- o2ib 192.168.1.4, tcp0 10.1.254.5
compute-0-0 		- o2ib 192.168.1.10, tcp0 10.1.254.10
compute-0-1 		- o2ib 192.168.1.11, tcp0 10.1.254.11
compute-0-*			-o2ib 192.168.1.*,tcp0 10.1.254.*
compute-1-*			-tcp0 10.1.253.*

What i think i need is
in modprob.conf
options lnet 'ip2nets="o2ib0(ib0) 192.168.*.*; tcp(eth0) 10.1.*.*"' \
'routes="tcp 192.168.1.[3-5]@o2ib0; o2ib 10.1.254.[10-11]@tcp0"

Does this look right?
