Question 3 of 27

4. 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 with the best metric if there is more than one route available.

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

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.

5. What does the below HSRP virtual MAC address tell you?

Gateway-1#show standby[Trunkated]Standby router is 192.168.1.2, priority 100 (expires in 9.019 sec)Priority 105 (configured 105)IP redundancy name is “hsrp-Fa0/0-1” (default)State is Active2 state changes, last state change 00:09:45Virtual IP address is 172.16.1.254Active virtual MAC address is 0000.0c07.ac02Local virtual MAC address is 0000.0c07.ac02 (v1 default)Hello time 3 sec, hold time 10 secNext hello sent in 2.423 secsPreemption disabledActive router is local
