Configuring Multi-Process and Multi-Area DCN
If a GNE belongs to multiple processes and areas, multi-process and multi-area DCN can be configured so that the GNE can manage all the NEs in different processes and areas.
Background Information
On large-scale DCNs, different NEs are usually deployed in multiple processes and areas. In this situation, allocate interfaces on the GNE to different processes and areas and enable the GNE to advertise its NEIP address to these processes and areas so that the GNE can learn information about the DCN core routing tables of all the NEs in these processes and areas and manage the NEs.
Procedure
- Run system-view
The system view is displayed.
- Run interface interface-type interface-number
The interface view is displayed.
- Run dcn ospf enable [ process-id ] area area-id
A process and an area are specified for DCN serial interfaces or sub-interface 4094.
In most cases, the network (OSPF) command adds an interface to the specified process and area. However, this command does not apply to DCN serial interfaces or sub-interface 4094 because they borrow the same IP address.
- Run quit
The system view is displayed.
- Run dcn
The DCN view is displayed.
- Run advertise neip
The GNE is enabled to advertise its NEIP address to multiple processes and areas.
- Run commit
The configuration is committed.
