Description |
|---|---|
|
LSP IDs are auto-assigned by the originating IS-IS node. The LSP ID consists of three sections. The first 6 bytes represent the system ID for that node, followed by a single byte value for the pseudonode generated by that router, and finally a fragment byte that starts at zero. For example, if a router system ID is 1800.0000.0029, the first LSP ID is 1800.0000.0029.00-00. If there are too many routes, LSP ID 1800.0000.0029.00-01 is created to contain the excess routes. If the router is the Designated Intermediate System (DIS) on a broadcast network, a pseudonode LSP is created. Usually the internal circuit ID is used to determine the ID assigned to the pseudonode. For example, for circuit 4, a LSP pseudonode with ID 1800.0000.0029.04-00 is created. The router learns hostnames and uses the hostname in place of the system ID. Example of LDP IDs are the following:
|
|
Displays the sequence number of the LSP that allows other systems to determine whether they have received the latest information from the source. |
|
Displays the checksum of the entire LSP packet |
|
Displays the amount of time, in seconds, that the LSP remains valid |
|
|
|
Displays a sum of all the configured level 1 and level 2 LSPs |
|
Displays a unique identifier for each LSP composed of SysID, Pseudonode ID, and LSP name |
|
Displays the remaining time until the LSP expires |
|
Displays the version or protocol ID extension. This value is always set to 1. |
|
Displays the PDU type number |
|
Displays the version or protocol ID extension. This value is always set to 1. |
|
Displays the maximum number of area addresses supported |
|
Displays the length of the system ID field (0 or 6 for 6 digits) |
|
Displays the actual length of the PDU |
|
Displays the amount of memory space allocated for the LSP |
|
Displays the area addresses to which the router is connected |
|
Displays the data protocols that are supported |
|
Displays the name of the router originating the LSP |
|
|
|
Displays the routers running interfaces to which the router is connected |
|
Displays a 32-bit metric. A bit is added for the ups and downs resulting from level 2 to level 1 route leaking. |
|
Displays the IP addresses that the router knows about by externally originated interfaces |
|
Displays a routing metric used in the IS-IS link-state calculation |
