9.3. DHCPv4-relay point to dhcp ip pool
When the service VLAN in the OLT is different from the upper equipment address pool VLAN, by using
"dhcp-relay" service VLAN need to jump to the
VLAN interface address where DHCP address pool is
at.
This command is used to set how three-layer DHCP Relay will fill in the message source IP. DHCP
Relay can set the IP source address and the IP address of the unicast DHCP message when unicasting
the user's broadcast message to DHCP server.
Configure global DHCP Relay:
OLT(config)# ip dhcp-relay enable
Configure service VLAN and allocated interface address:
OLT (config) # vlan 102
OLT (config-vlan102) # exit
OLT (config) # interface vlanif102
OLT (config-vlanif102) # ip address 12.0.0.1/24
Configure DHCP Relay layer three function:
OLT (config-vlanif102) # ip dhcp relay-agent
OLT (config-vlanif102) # ip dhcp relay-server-address 22.0.0.1
OLT (config-vlanif102) # ip dhcp relay-server-address 22.0.1.1
OLT (config-vlanif102) # ip dhcp relay-server-address 22.0.3.1
OLT (config-vlanif102) # ip dhcp relay-server-address 22.0.4.1
Configure static route:
OLT(config)# ip route
OLT(config-ip-route)# ip route 22.0.0.0/16 22.0.0.2 OLT(config-ip-
route)# exit
