Do not complete this procedure until you confirm the role of the node within the network. It will be either an IS Level 1 or an IS Level 1/Level 2. This decision must be carefully considered. For additional information about OSI provisioning, refer to the “Management Network Connectivity” chapter of the Cisco ONS 15600 SDH Reference Manual.

LSP buffers must be the same at all NEs within the network, or loss of visibility could occur. Do not modify the LSP buffers unless you are sure that all NEs within the OSI have the same buffer size.

LSP buffer sizes cannot be greater than the LAP-D MTU size within the OSI area.

Verify that all L1/L2 virtual routers on the NE must reside in the same area. This means that all neighboring virtual routers must have at least one common area address.

In node view, click the Provisioning > OSI > Main Setup tabs.

Choose one of the following routing modes:

•Intermediate System Level 1—The ONS 15600 SDH performs OSI IS functions. It communicates with IS and ES nodes that reside within its OSI area. It depends upon an IS L1/L2 node to communicate with IS and ES nodes that reside outside its OSI area.

•Intermediate System Level 1/Level 2—The ONS 15600 SDH performs IS functions. It communicates with IS and ES nodes that reside within its OSI area. It also communicates with IS L1/L2 nodes that reside in other OSI areas. Before choosing this option, verify the following:

–The node is connected to another IS Level 1/Level 2 node that resides in a different OSI area.

–The node is connected to all nodes within its area that are provisioned as IS L1/L2.
