Persistent looping : It is a kind of problem that will remain forever if we cant do anything. Transient looping: : these kind of problem occur for a small duration 0 votes 0 votes student2018 commented Apr 23, 2017 reply Follow Share suppose in this image A sends DV to its neighbours (B,C,D) in DVR even in Link State A sends information to its neighbours(B,C,D) then whats the difference I learnt it as flooding is done in Link state But i could n't get how actucally vector moves in these 2 0 votes 0 votes akash.dinkar12 commented Apr 23, 2017 reply Follow Share In DVR , A sends its distance vectors to only in its neighboures (B , C , D), thats why it is based on local knowledge. In LSR, Every station or router will create "link state packets" link : It is nothing but edge state : It indicates that whether router is up or down.. In LSR the very first step is every node or router will find out information about neighboures , links , and distances by using hello packets. second thing is , in LSR every router is going flood the information to every other router 0 votes 0 votes Xylene commented Aug 9, 2017 reply Follow Share We can solve looping using split horizon, then how is it persistent? 0 votes 0 votes Please log in or register to add a comment.
