Table 261 Description on the fields of the debugging isis update-packet command

Field Description

UPDT: Received LSP Not processed on P2P Circuit due to Low Memory, Sending Acknowledgement)

UPDT: LSP newer than data base copy.

The received LSP was dropped due to insufficient memory of the P2P interface and an acknowledgement packet was sent.

The received LSP is newer and the local LSDB is updated.

UPDT: Expired Own LSP received. Just Acknowledging.

UPDT: LSP’s SeqNumber is 0.

Remaintime of the received LSP is 0 and therefore only an acknowledge packet is sent.

The LSP’s sequence number is 0, which is invalid.

UPDT: Err, Area Addr Option in pseudonode Lsps !!

Error: The area address TLV exists in pseudonode LSPs.

Examples # Router A and Router B are interconnected. On Router A, an IS-IS process is created with a System ID of 0000.0000.0001 and router type of level-1-2; IS-IS is enabled on VLAN-interface 100 with the IP address 100.1.1.1/24. On Router B, another IS-IS process is created with a System ID of 0000.0000.0002 and router type of level-1-2; IS-IS is enabled on VLAN-interface 100 with the IP address 100.1.1.2/24. RTA and RTB are in the same area 49.0001. Enable IS-IS adjacency packet debugging on Router A.

ISIS-1-ADJ: Declaring as DIS,DIS Type L1,on Vlan100, Old DIS (null), New DIS 0000.0000.0001.01.

//An L1/L2 neighbor relationship was established between Router A and Router B, and a DIS election was performed.

#VLAN-interface 100 on Router A is connected to VLAN-interface 100 on Router B. An IS-IS process is created on Router A and Router B respectively. Enable interface circuit debugging for IS-IS. Disable IS-IS and then enable it on VLAN-interface 100 of Router A.
