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])

Description

There were more than three area addresses and the local area address was discarded.

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 device, 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

1. 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.

2. 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 device.

  • If so, go to Step 4.
  • If not, go to Step 3.

3. Collect log information and configuration information, and then contact technical support personnel.

4. End.
