Question 1 – Routing Protocols
a) Consider the following network. With the indicated link costs, use Dijkstra’s shortest-path
algorithm to compute the shortest path from x to all network nodes. Show how the algorithm
works by computing a table.
b) Consider the three-node topology shown below. Let the link costs be c(x,y) = 3, c(y,z) = 6, c(z,x) =
4. Compute the distance tables after the initialization step and after each iteration of the
distance-vector algorithm.
c) Consider the count-to-infinity problem in the distance vector routing. Will the count-to-infinity
problem occurs if we decrease the cost of a link? Why? How about if we connect two nodes
that do not have a link?
a) Consider a router that interconnects three subnets: Subnet 1, Subnet 2, and Subnet 3. Suppose
all of the interfaces in each of these three subnets are required to have the prefix 223.1.17/24.
Also suppose that Subnet 1 is required to support up to 63 interfaces, Subnet 2 is to support up
to 95 interfaces, and Subnet 3 is to support up to 16 interfaces. Provide three network
b) Consider a subnet with. Give an example of one IP address that can be assigned to this network. Suppose an ISP owns the block of
addresses of the form . Suppose it wants to create four subnets from this
block, with each block having the same number of IP addresses. What are the prefixes for the four subnets?
