Question 57
CSNAT2 marksNeeds review
Consider a network with three routers P, Q, R shown in the figure below. All the links have cost of unity.
The routers exchange distance vector routing information and have converged on the routing tables, after which the link Q–R fails. Assume that P and Q send out routing updates at random times, at the same average rate. The probability of a routing loop forming (rounded off to one decimal place) between P and Q, leading to count-to-infinity problem, is __________.
