DHCP Relay Agent Configuration for IPv6

This section shows how to configure the DHCPv6 relay agent.

DHCPv6 Relay Agent

OcNOS#configure terminal	Enter configure mode.
OcNOS(config)#ipv6 dhcp relay server-group dhcpv6-relay-gp	Configure relay server-group group name in global mode.
OcNOS(dhcp6-relay-group)#server 2001::2	Configure server address `2001::2`.
OcNOS(dhcp6-relay-group)#commit	Commit the candidate configuration to the running configuration.
OcNOS(dhcp6-relay-group)#exit	Exit DHCPv6 relay group.
OcNOS(config)#interface xe8	Enter interface mode `xe8`.
OcNOS(config-if)#ipv6 address 2001::3/64	Configure IPv6 address `2001::3/64` on the interface `xe8`.
OcNOS(config-if)#ipv6 dhcp relay uplink	Configure relay uplink on the device connecting the server.
OcNOS(config-if)#ipv6 dhcp relay server-select dhcpv6-relay-gp	Configure relay server-select group name on the device connected to the server.
OcNOS(config-if)#commit	Commit the candidate configuration to the running configuration.
OcNOS(config-if)#exit	Exit interface mode.
OcNOS(config)#interface xe15	Enter interface mode.
OcNOS(config-if)#ipv6 address 3001::2/64	Configure IPv6 address on the interface `xe15`.
OcNOS(config-if)#ipv6 dhcp relay	By default, this will be enabled. This command starts the IPv6 dhcp relay service.
OcNOS(config-if)#commit	Commit the candidate configuration to the running configuration.
OcNOS(config-if)#exit	Exit interface mode.
OcNOS(config)#ipv6 dhcp relay server-group dhcpv6-relay-gp	Configure relay server-group group name in global mode.
OcNOS(dhcp6-relay-group)#server 4001::2	Configure server address `4001::2`.
OcNOS(dhcp6-relay-group)#commit	Commit the candidate configuration to the running configuration.
OcNOS(dhcp6-relay-group)#exit	Exit DHCPv6 relay group.
OcNOS(config)#interface xe11	Enter interface mode.
OcNOS(config-if)#ipv6 address 4001::3/64	Configure IPv6 `4001::3/64` address on the interface `xe11`.
OcNOS(config-if)#ipv6 dhcp relay uplink	Configure relay uplink on the device connecting the server.
OcNOS(config-if)#ipv6 dhcp relay server-select dhcpv6-relay-gp	Configure relay server-select group name on the device connected to the server.
OcNOS(config-if)#commit	Commit the candidate configuration to the running configuration.
OcNOS(config-if)#exit	Exit interface mode.
