Question 45
CSMSQ2 marksNeeds review
Consider a computer network using the distance vector routing algorithm in its network layer. The partial topology of the network is as shown below.
The objective is to find the shortest-cost path from the router
to routers
and
. Assume that
does not initially know the shortest routes to
and
. Assume that
has three neighboring routers denoted as
,
, and
. During one iteration,
measures its distance to its neighbours
,
, and
as 3, 2, and 5, respectively. Router
gets routing vectors from its neighbours that indicate that the distance to router
from routers
,
, and
are 7, 6, and 5, respectively. The routing vector also indicates that the distance to router
from routers
,
, and
are 4, 6, and 8, respectively. Which of the following statement(s) is/are correct with respect to the new routing table of
, after update during this iteration?Your answerSelect all correct options. You can choose more than one.
