DLP- A544 Change the OSI Routing Mode

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

Step 1 Verify the following:

•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.

•For OSI L1/L2 to ES routing mode changes, only one L1/L2 virtual router and no more than one subnet can be configured.

•For OSI L1 to ES routing mode changes, only one L1 virtual router and no more than one subnet can be configured.

Step 2 In node view, click the Provisioning > OSI tabs.

Step 3 Choose one of the following routing modes:

•End System—The ONS 15454 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 15454 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.

Note Changing a routing mode should be carefully considered. Additional information about OSI ESs and ISs and the ES-IS and IS-IS protocols are provided in the “Management Network Connectivity” chapter of the Cisco ONS 15454 Reference Manual.

Step 4 Although Cisco does not recommend changing the LSP (Link State Protocol Data Unit) buffer sizes, you can adjust the buffers in the following fields:

•L1 LSP Buffer Size—Adjusts the Level 1 link state PDU buffer size.

•L2 LSP Buffer Size—Adjusts the Level 2 link state PDU buffer size.

Step 5 Return to your originating procedure (NTP).
