# This script configures a scenario with 2 topologies:		                   #

#        - Topology 1 with LAC and DHCPv6 Client							   #

#        - Topology 2 with LNS and DHCPv6 Server 							   #

# The script does:										                       #

#    	 - start/stop protocol												   #

#		 - collect and display DHCP statistics       						   #

# This script configures a scenario with 2 topologies:		                   #

#        - Topology 1 with LAC and DHCPv6 Client							   #

#        - Topology 2 with LNS and DHCPv6 Server 							   #

# The script does:										                       #

#    	 - start/stop protocol												   #

#		 - collect and display DHCP statistics       						   #
