hey guys ,
i guess the conversation is leading a different
direction .... what i meant to ask is ... the lab
scenerio have not specified where( which area ) ... so
i just need to know is there any thumb rule or any
logic behind it.... cause when i glance at the answer
configuration sometimes they are in area 0 and
sometimes they are not ... so i just need to know ..
how critical is this placement of loopback IP in a
particular area ...
I hope im clear this time ...
thanx everyone ..
