ISIS/2/ISIS_MANUAL_ADDRESS_DROPS
Message
ISIS/2/ISIS_MANUAL_ADDRESS_DROPS: Some area addresses were discarded because the number of area addresses exceeded three. (isisSysInstance=[isisSysInstance], isisSysLevelIndex=[isisSysLevelIndex], isisManAreaAddr=[isisManAreaAddr], isisManAreaAddrExistState=[isisManAreaAddrExistState])
Parameters
| Parameter Name | Parameter Meaning |
|---|---|
[isisSysInstance] |
ID of an IS-IS process |
[isisSysLevelIndex] |
IS-IS level |
[isisManAreaAddr] |
IS-IS area address |
[isisManAreaAddrExistState] |
State of an area address |
Possible Causes
On a Level-1-2 , IS-IS leaked Level-1 area addresses to the Level-2 area, increasing the area addresses of the Level-2 area to more than 3. In this case, IS-IS uses the top three smallest area addresses as the Level-2 area addresses, causing address loss in the local Level-2 area.
Procedure
- Run the display isis lsdb level-1 verbose command to view details about the Level-1 LSDB. Based on the information
about the AREA ADDR field in the LSP with the fragment number being 0, you can determine whether the number of Level-1 area addresses exceeds 3.
- If so, go to Step 2.
- If not, go to Step 3.
- Run the undo network-entity command (exercise caution when running this command) in the IS-IS view to delete the IS-IS area addresses, and then run the network-entity command in the IS-IS view to configure new IS-IS area addresses to ensure that there are not more than three different IS-IS area addresses in the Level-1 area that is connected to
the Level-1-2 router. Run the display isis lsdb command to check whether the Level-1 area addresses are the same as the Level-2 area addresses in the LSPs with the fragment
number being 0 on the local .
- If so, go to Step 4.
- If not, go to Step 3.
- Contact technical support personnel technical support personnel.
- End.
