Which of the following statements are TRUE regarding the following output? (Choose all that apply.)
A.
There are four default routes on this router.
B.
There are four physically connected interfaces on this router.
C.
This router is running EIGRP.
D.
The metric for the routes learned via a routing protocol is 90.
E.
A packet for the 192.168.52.0 network will be load-balanced across two paths.
Explanation:
This router is running EIGRP and a packet for the 192.168.52.0 network will be load-balanced across two paths.
EIGRP routes display with a D code in the leftmost column of the show ip route command. The D stands for Diffusing Update Algorithm (DUAL), which is the
algorithm used by EIGRP to determine the best and potential backup paths to each remote network. There are four EIGRP-learned routes in this exhibit.
When two routes with equal metrics exist in the routing table, EIGRP will send packets using both paths. In the output there are two routes listed for the
192.168.52.0 network. Both have thesame metric value (2172416). Therefore, packets will be sent to that network via the Serial 0/1/0 interface to the neighbor at
192.168.15.254 and via the Serial 0/0/0 interface to the neighbor at 192.168.15.5. Both paths, either directly or indirectly, lead to the 192.168.52.0 network, and both
paths have the same cost.
There are not four default routes on this router. The D represents EIGRP-learned routes, not default routes. There is one default route, as indicated by the line of
output that says Gatewayof last resort is 192.168.15.1 to network 0.0.0.0. Because Serial0/1/0 is directly connected to the 192.168.15.0 network, packets that aredestined for networks not found in the routing table will be sent out on that interface.
The C in the leftmost column of the show ip route command represents directly connected networks, of which there are four in the exhibit. Closer examination,
however, reveals that one of these entries (for network 192.168.33.0) is connected to a loopback interface (Loopback1), as opposed to a physical interface:
C 192.168.33.0 is directly connected, Loopback1
Loopback interfaces are virtual, software interfaces that appear in the routing table, but do not represent a physical interface on the router. Therefore, there are
three physically connected interfaces on this router, not four.
The metric for the routes learned via a routing protocol is not 90. The 90 in the scenario output is the administrative distance (AD) of the route, and the 2196545 is
the metric value (see below):
D 192.168.25.0 [90/2196545] via 192.168.20.254, 0:01:20, Serial0/0/1
