Variable Definitions
The following table defines parameters for the show isis lsdb command.
|
Variable |
Value |
|---|---|
|
detail |
Displays detailed information. |
|
home |
Displays the IS-IS LSDB information that the system configures in the home area. |
|
level {l1|l2|l12}] |
Displays the LSDB for the specified level: l1, l2, or l12. |
|
local |
Displays IS-IS local LSDB information. |
|
remote |
Displays the IS-IS LSDB information that the system configures in the remote area. |
|
sysid <xxxx.xxxx.xxxx> |
Displays the LSDB for the specified system ID. |
|
lspid <xxxx.xxxx.xxxx.xx-xx> |
Displays the LSDB for the specified LSP ID. |
|
tlv <1–236> |
Displays the LSDB by TLV type. |
The following table defines parameters for the show isis adjacencies command.
|
Variable |
Value |
|---|---|
|
home |
Displays the IS-IS adjacencies that the system configures in the home area. |
|
remote |
Displays the IS-IS adjacencies that the system configures in the remote area. |
The following table defines parameters for the clear isis command.
|
Variable |
Value |
|---|---|
|
lsdb |
Clears the IS-IS Link State Database (LSDB). The command clears learned LSPs only. The command does not clear local generated LSPs. As soon as the platform clears the LSDB the LSP synchronization process starts immediately and the LSDB synchronizes with its neighbors. |
