[j-nsp] New to Juniper: loopback interface address for the re0 configuration group?

[raf]

In this example Raphael set two different addresses for fxp0 for each RE 
(.10, .11) and a 'virtual' one (.9) which reside only on the master RE.

I do not recommend the use of fxp0, (rather use in -band management, and 
serial oob in case of failure), unless you are totally sure of your 
management network.
