LPI Exam 304-200 Topic 11 Question 9 Discussion

While setting up a load-balanced HTTP service, Linux Virtual Server was configured with the commands:

ipvsadm -A -t 198.51.100.2:80 -s rr

ipvsadm -a -t 198.51.100.2:80 -r 192.168.10.1:80 -m

ipvsadm -a -t 198.51.100.2:80 -r 192.168.10.2:80 -m

and all backend servers are using the LVS host as the default router. Which additional command has to be issued on the LVS host in order to correctly handle incoming HTTP traffic?
