Step 2
Verify the DHCP service status by entering the following command in Exec Mode:
show dhcp service status
DHCPv6 Service Configuration
The system can be configured to use the Dynamic Host Control Protocol (DHCP) for IPv6 to enable the DHCP servers
to pass the configuration parameters such as IPv6 network addresses to IPv6 nodes. DHCPv6 configuration is done
within an APN.
These instructions assume that you have already configured the system level configuration as described in System
Administration Guide and APN as described in P-GW PDN Context Configuration section of this chapter.
To configure the DHCPv6 service:
Step 1
Create the DHCPv6 service in system context and bind it by applying the example configuration in the DHCPv6 Service
Creation section.
Step 2
Configure the DHCPv6 server and other configurable values for Renew Time, Rebind Time, Preferred Lifetime, and
Valid Lifetime by applying the example configuration in the DHCPv6 Server Parameter Configuration section.
Step 3
Configure the DHCPv6 client and other configurable values for Maximum Retransmissions, Server Dead Tries, and
Server Resurrect Time by applying the example configuration in the DHCPv6 Client Parameter Configuration section.
Step 4
Configure the DHCPv6 profile by applying the example configuration in the DHCPv6 Profile Configuration section.
Step 5
Associate the DHCPv6 profile configuration with the APN by applying the example configuration in the Associate
DHCPv6 Configuration section.
Step 6
Verify your DHCPv6 Service configuration by following the steps in the DHCPv6 Service Configuration Verification
section.
Step 7
Save your configuration as described in the Verifying and Saving Your Configuration chapter.
DHCPv6 Service Creation
Use the following example to create the DHCPv6 service to support DHCP-based address assignment:
configure
context <dest_ctxt_name>
dhcpv6-service <dhcpv6_svc_name>
bind address <ipv6_address> port <port>
end
Notes:
To ensure proper operation, DHCPv6 functionality should be configured within a destination context.
DHCP client rapid-commit: disabled
DHCP chaddr validation: enabled
