Figure 1 Networking example for the IP over DCC solution

Figure 1 shows a transmission network that is comprised of both OptiX equipment and the third-party equipment that supports the IP over DCC feature. The steps to plan the DCN are as follows:

1. Select NE101 that is the closest to the Web LCT as the gateway NE.
2. As the third-party equipment uses the DCC bytes D1 to D3, it is not required to modify the DCCs of the NEs.

3. Allocate IDs and IP addresses for all the NEs according to the situation of the network. The subnet mask of all the NEs is 255.255.0.0.

4. Plan IP routes.

   • As the number of NEs is smaller than 64 and all the NEs support the OSPF protocol, configure all the NEs to the same OSPF area.
   • The Web LCT and the gateway NE (NE101) are in the same Ethernet segment. The gateway NE can obtain the routes to all other NEs through the OSPF protocol. Therefore, the Web LCT can access any NE in the gateway mode, and you do not need to set any route.
   • As there are routers between the third-party NMS and NE101, using only dynamic routes cannot achieve the connection between the third-party equipment and the Web LCT. Therefore, set static routes on NE101, NE102, the Web LCT server, and the routers.
