What should be done?

You add the following commands into a routed topology: router eigrp 1 variance 3 traffic-share min
across-interfaces. Users now complain about voice quality in your VoIP system. What should be
done?

A.
Add the command: router eigrp 1 traffic-share voice interface fast 0/0.

B.
Reconfigure EIGRP to recognize voice packets.

C.
Remove the variance from the configuration.

D.
Reconfigure the VoIP system to use RTP sequence number headers.

E.
Use an H.323 gatekeeper for your VoIP system to negotiate an H.245 uneven packet buffer.

F.
Reconfigure EIGRP to version 2.

Explanation:
Traffic-share min command causes EIGRP to divide traffic only among the routes with the best
metric. When the traffic-share min command is used with the across-interfaces keyword, an

attempt is made to use as many different interfaces as possible to forward traffic to the same
destination.
Therefore with the configuration above, EIGRP will only use equal-cost load-balancing feature
even when the variance command is used. However, if you use both the traffic-share min
command and variance command, even though traffic is sent over the minimum-cost path only, all
feasible routes get installed into the routing table, which decreases the convergence times.
