Well this is a simple post . i was searching the web for what does it mean by Wire and Hub mode in Tipping point IPS for interfaces mode .
after long search it is simple .
let say you have interface it has A,B side
Hub mode : if side A went down ,site B still up and viceversa
Wire mode : if side A went down , side B goes down also
which one is good , for Me is Wire mode why ? .. simple if you are using static routes or interface route Hub can cus you problem since interface still up unless you use SLA or Dynamic routing .
