Service Planning

The service planning information contains all the parameters required for configuring the NE data.

The convergence network is a PSN. Therefore, NE management uses the inband DCN.
The OptiX radio NEs and third-party radio NEs support the OSPF protocol. In addition, the number of NEs on each network is not more than 64. Therefore, multiple OSFP areas are configured, with route aggregation used to decrease the size of the routing table.
Select NE1, the NE on the convergence network which is the closest to the NMS, as the gateway NE.
The Huawei NMS and third-party NMS are located at the same place and NE1 is located at another place. Therefore, construct the external DCN between the Huawei and third-party NMSs and NE1 through a router.
Each port with the inband DCN enabled uses the IP protocol.

The entire network is divided into three OSPF areas. The convergence network is the backbone area (Area 0), in which all NE IP addresses belong to the 129.9.0.0 network segment. The edge network is divided into Area 1 and Area 2 (non-backbone areas). The NE IP addresses in Area 1 belong to the 129.10.0.0 network segment and the NE IPs in Area 2 belong to the 129.11.0.0 network segment. Area1 and Area2 are non-stub areas.
The OptiX NMS and the third-party NMS belong to the 10.2.0.0 network segment and communicate with the gateway NE (NE1, whose IP address is 129.9.0.1) on the backbone area respectively through RT1 (IP address: 10.2.0.150) and RT2 (IP address: 129.9.0.100).
NE4 (IP address: 129.9.0.4) functions as an ABR in Area 1, with its NE IP address on the same network segment (129.9.0.0) as those of NEs in Area 0. The interface IP address of the ABR is 129.10.0.100 and is on the same network segment as the other NEs in Area 1.
NE7 (IP address: 129.9.0.7) functions as an ABR in Area 2, with its NE IP address on the same network segment (129.9.0.0) as those of NEs in Area 0. The interface IP address of the ABR is 129.11.0.100 and is on the same network segment as the other NEs in Area 2.
Automatic route aggregation is enabled for Area 1 and Area 2.

Plan the following route information between the OptiX radio NEs.
- On NE1 (gateway NE in the backbone area), configure a static route to the Huawei NMS (IP address: 10.2.0.100) and a static route to the third-party NMS (IP address: 10.2.0.200).
- On NE1, enable the OSPF route flooding function, enabling NE2, NE3, NE4, NE5, and NE6 to obtain routes to the Huawei NMS and enabling NE7 and NE8 to obtain the routes to the third-party NMS.
In addition, plan the following routes:
- On the Huawei NMS, configure a static route to the gateway OptiX NE (IP address: 129.9.0.1). The gateway uses the router interface IP address, 10.2.0.150.
- On the third-party NMS, configure a static route to the third-party gateway NE (IP address: 129.9.0.7). The gateway uses the router interface IP address, 10.2.0.150.
- On RT1 and RT2, configure related routes.
- On the third-party gateway NE (IP address: 129.9.0.7), create Area 2 and specify the interface IP address as 129.11.0.100.

On the GE packet-switched ring, NEs use the inband DCN for DCN communication. The management VLAN ID takes the default value 4094, and the inband DCN bandwidth is set to 1000 kbit/s.
On the edge network, NEs use DCC channels for DCN communication.
NE3 and NE7 use network management ports for DCN communication between each other.
