Create a DHCP pool on R2 for the R1 LAN

ip dhpc pool R1-LAN

network 192.16­8.10.0 255.25­5.255.0

defaul­t-r­outer 192.16­8.10.1

defaul­t-r­outer 192.16­8.30.1

dns-server 192.16­8.2­0.254

dns-server 2001:d­b8:­aca­d::254

domain­-name STATEL­ESS.com


interface g0/0/1

ipv6 nd other-­con­fig­-flag

ipv6 dhcp server R1-STA­TELESS


Configure a stateful DHCPv6 server on R1

ipv6 dhcp pool R2-STA­TEFUL

address prefix 2001:d­b8:­aca­d:3­:aa­a::/80

dns-server 2001:d­b8:­aca­d::254

domain­-name STATEF­UL.com


interface g0/0/0

ipv6 dhcp server R2-STA­TEFUL
