perfSONAR User Q&A and Other Discussion

["Roderick Mooi" <>]

Hi Christopher

I have some experience with dual-homed hosts on ps 3.3. so perhaps I can 
help. Some questions first:
1. How did you configure the dual-homing?
2. Do the interfaces share the same gateway (or gateway IP)?

Regards,

Roderick
