True

Question 1 of 27

2. What does the * indicate in the output below?

R2#show ip route 172.16.100.0 255.255.255.0Routing entry for 172.16.100.0/24Known via “eigrp 150”, distance 90, metric 2172416, type internalRedistributing via eigrp 150Last update from 150.1.1.1 on Serial0/0, 00:01:55 agoRouting Descriptor Blocks:* 150.1.1.1, from 150.1.1.1, 00:01:55 ago, via Serial0/0Route metric is 2172416, traffic share count is 1Total delay is 20100 microseconds, minimum bandwidth is 1544 KbitReliability 255/255, minimum

The asterisk (*) points to the interface where traffic shaping has been configured.

The asterisk (*) points to the interface over which the next packet is sent.

The asterisk (*) points to the first route learned by EIGRP.

The asterisk (*) points to the interface with the best metric if there is more than one route available.
