Usage
Use this command to associate or tie the DHCP service to a specific logical IP address previously configured
in the current context and bound to a port. Once bound, the logical IP address or interface is used in the
giaddr field of the DHCP packets.
When this command is executed, the DHCP service is started and begins the process of requesting addresses
from the DHCP server and storing them in cache memory for allocation to PDP contexts.
This command can also be used to configure MPLS labels for inbound and outbound traffic through this
