ISIS/2/ISIS_LSP_TOO_LARGE_TO_PROPAGATE

Message

ISIS/2/ISIS_LSP_TOO_LARGE_TO_PROPAGATE: ISIS attempt to propagate an LSP which is larger than the dataLinkBlockSize for the circuit. (isisSysInstance=[isisSysInstance], isisSysLevelIndex=[isisSysLevelIndex], isisCircIndex=[isisCircIndex], isisCircIfIndex=[isisCircIfIndex], isisPduLspSize=[isisPduLspSize], isisPduLspId=[isisPduLspId], ifIndex=[ifIndex], IfName=[IfName])

Description

IS-IS attempted to send an LSP whose length was greater than the MTU on an interface.

Parameters

Parameter Name	Parameter Meaning
isisSysInstance	Indicates the ID of the IS-IS process.
isisSysLevelIndex	Indicates the IS-IS level. 1: Level-1 2: Level-2
isisCircIndex	Indicates the index assigned by an IS-IS interface.
isisCircIfIndex	Indicates the IF index of an IS-IS interface.
isisPduLspSize	Indicates the length of an LSP.
isisPduLspId	Indicates the LSP ID.
ifIndex	Indicates the IF index of an interface.
IfName	Indicates the name of the interface.

Possible Causes

During LSP forwarding, the length of an LSP was greater than the MTU on an interface.

Procedure

Ensure that the MTUs of all interfaces are greater than the length of the LSP.
