The 3rd, if management plane has configured initialization route and fault-free, as shown in Figure 5, the initialization route of management plane configuration is the L1-L7 link; Automatically the initialization route L4-L6 link that deleting control plane calculates.
Wherein, management plane can be business and configures many initialization routes simultaneously, for example: and configurable L2-L8 link again, and priority is lower than the L1-L7 link.If business is recovered, select initialization route and the high L1-L7 link of priority of management plane configuration to be recovered; Business is recovered again, just selects the L2-L8 link.
Further, management plane can also be revised the initialization route of configuration, and the L1-L7 link of configuration is revised as to the L4-L6 link, and the L2-L8 link is revised as the L3-L5 link, and priority is lower than the L4-L6 link.Business is recovered, and selection is revised afterwards and the high initialization route of priority is recovered.
Further, management plane can also be cancelled the initialization route of configuration, cancels L4-L6 link, L3-L5 link; After cancelling the initialization route of configuration, control plane needs automatically to calculate the initialization route.
The 4th, the initialization route of management plane configuration all breaks down, and control plane needs automatically to calculate the initialization route.
As shown in Figure 6, management plane has configured initialization route L1-L7 link, L2-L8 link.If only have the L1-L7 link failure, control plane can not calculate the initialization route automatically, only has all faults of L1-L7 link, L2-L8 link, and control plane just needs automatically to calculate the initialization route.The initialization route calculated is the L3-L5 link.Business is recovered, and the initialization route L3-L5 link of selecting control plane automatically to calculate is recovered.
If L1-L7 link, L2-L8 link are as long as wherein an initialization routing failure disappears, the initialization route L3-L5 link that deleting control plane calculates automatically automatically.
