Am I missing something..
So you say:
10.1.0.1 Anycast (x50 boxes)
10.2.0.1 Non-anycast
is somehow different from
10.1.0.1 Anycast1 (x50 boxes)
10.2.0.1 Anycast2 (x50 boxes - different to anycast1)
In each scenario two systems have to fail to take out any one customer.. but
isnt the bottom one better for the usual pro anycast reasons?
