Binds the DHCP service
to a logical IP interface facilitating the system’s connection
to the DHCP server. This command also configures traffic from the
specified DHCP service bind address to use the specified Multiple
Protocol Label Switching (MPLS) labels.

Syntax
bind address ip_address [ nexthop-forwarding-address nexthop_ip_address [ mpls-label
input in_mpls_label_value output out_mpls_label_value1 [ out_mpls_label_value2 ] ] ]
no bind address ip_address
no
Removes a previously
configured binding.
address ip_address
Specifies the IP address
of an interface in the current context through which the communication
with the DHCP server occurs. ip_address must
be expressed in IPv4 dotted-decimal notation.
nexthop-forwarding-address nexthop_ip_address
Specifies the next
hop gateway address for in MPLS network to which the packets with MPLS
labels will be forwarded. nexthop_ip_address must
be expressed in IPv4 dotted-decimal or IPv6 colon-separated-hexadecimal notation.
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.
output out_mpls_label_value1 [ out_mpls_label_value2 ]
Adds the MPLS label
to the outbound traffic sent from the configured DHCP service bind address ip_address.
The labels out_mpls_label_value1 and out_mpls_label_value2 identify
the MPLS labels to be added to packets sent from the specified dhcp
service bind address.
out_mpls_label_value1 is
the inner output label and must be an integer from 16 through 1048575.
out_mpls_label_value2 is
the outer output label and must be an integer from 16 through 1048575.
IMPORTANT:
This keyword is license-enabled
and available with valid MPLS feature license only.
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 DHCP address.
Only one interface
can be bound to a service.
For
DHCP over MPLS feature to work in StarOS 9.0 onward 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.
CAUTION:
As a part of DHCP
over MPLS configuration, the mpls-label input keyword
in the bind address command
is also a critical parameter for the DHCP-Service. Any change in
its value will result in DHCP-service restart and clearing of the
existing calls.
Example:
The following command
binds the DHCP service to the interface with an IP address of 1
92.168.1.210:
bind address 192.168.1.210
