[Lustre-discuss] How to configure routing

[Balagopal Pillai]

Hi,

          Interesting scenario if routing between public and private 
subnets for mounting lustre filesystem is possible
without disturbing the network admins for public subnet :-) One way 
around would be
to build tunnels like ipip for example between the gateway machine on 
the cluster
that has access to both nets and with other hosts on the public net. 
Then Lustre mount
could work over the tunnel with static routes to access the MGS/MDS/OST 
over the tunnel.

Regards
Balagopal
