The following table describes the fields for the show isis lsdb command.
|
Parameter |
Description |
|---|---|
|
LSP ID |
Indicates the LSP ID assigned to external IS-IS routing devices. |
|
LEVEL |
Indicates the level of the external router: l1, l2, or l12. |
|
LIFETIME |
Indicates the maximum age of the LSP. If the max-lsp-gen-interval is set to 900 (default) then the lifetime value begins to count down from 1200 seconds and updates after 300 seconds if connectivity remains. If the timer counts down to zero, the counter adds on an additional 60 seconds, and then the LSP for that router is lost. This situation happens because of the zero age lifetime, which is detailed in the RFC standards. |
|
SEQNUM |
Indicates the LSP sequence number. This number changes each time the LSP is updated. |
|
CKSUM |
Indicates the LSP checksum. The checksum is an error checking mechanism used to verify the validity of the IP packet. |
|
HOST-NAME |
Indicates the host-name. |
