69. Router MSR-1 is interconnected with MSR-2 and MSR-3 respectively. In the routing table of
MSR-1, there is a RIP route learned from MSR-2 to the destination network segment 120.10.12.0/24.
Its Cost is 3; at this time, MSR-1 also receives a RIP route from MSR-3 that is still destined for the
destination network segment 120.10.12.0/24, and its Cost is 15, then ______.
A. The routing table of MSR-1 will not be updated, and the routes for this network segment learned
from MSR-2 will still be retained.
B. The routing table of MSR-1 will be updated to the route with a cost of 15 learned from MSR-3.
