End System—The ONS 15454 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 15454 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.
–
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 SDH Reference Manual.
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.
This task allows you to edit the OSI router configuration, including
enabling and disabling OSI routers, editing the primary area address, and
creating or editing additional area addresses.
