Usage
Use this command to enable the DHCP-over-MPLS support and to associate/disassociate a pre-configured
VRF context to a DHCP service for this feature.
By default the VRF is NULL, which means that DHCP service is bound with binding address given by
VRF context to a DHCP service for this feature.
By default the VRF is NULL, which means that DHCP service is bound with binding address given by
command only.
VRF is not a critical parameter for the DHCP Service but bind address is a critical parameter for DHCP
Service, and while starting DHCP Service, if this command is configured, then the bind address should be
present in that VRF, and If this command is not configured, bind address should be present in the context
where DHCP Service is configured.
For DHCP over MPLS feature to work in StarOS 9.0 onward this command must be configured in DHCP
service. Without this command the DHCP service using MPLS labels will not be started.
