nexthop_ip_address
must be expressed in IPv4 dotted-decimal or IPv6 colon-separated-hexadecimal
notation.
Important:
In the case of DeWAG service, this option must not be configured.
mpls-label input in_mpls_label_value
Specifies the MPLS label to identify inbound traffic destined for the configured DHCP service bind address
ip_address
.
in_mpls_label_value
is the MPLS label that will identify inbound traffic destined for the configured
DHCP service and must be an integer from 16 through 1048575.
Important:
This keyword is license-enabled and available with valid MPLS feature license only.
Caution:
For DHCP over MPLS feature to work in StarOS 9.0 onward the
dhcp ip vrf
command must be
configured in DHCP service. Without
dhcp ip vrf
command the DHCP service using MPLS labels will not be started
as a part of a DHCP over MPLS configuration. In release 9.0 onward this keyword is a critical parameter for the DHCP-
Service. Any change in its value will result in DHCP-service restart and clearing of the existing calls.

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.
