Consider Dijkstra's algorithm in linked state routing protocol at node $u.$ Professor Ram first sets the route for each directly connected node $v.$ to be the link connecting $u$ to $v.$ Ram then implements the rest of the algorithm correctly, aiming to produce minimum cost ... and link costs where all routing table entry will be correct. $D)$ Both $A)$ and $B)$ How Dijkstra working here?
Consider a very large network $10000$ routers. Two host $A$ and $B$ connected with this network. Host $A$ sends a data to host $B$. and after some unit of time host $A$ receives $ICMP$ time exceed message for the samedata packet. The number of router ... some distance some ICMP message generated? Say if $ICMP$ message generated in $9999th$ router, then where it give error of time exceed message?
