Description: The maximum size of LSPs and SNPs originated by this Intermediate System at this level. This object follows the replaceOnlyWhileDisabled behavior.

What is isisSysLevelOrigLSPBuffSize?

Sets the maximum size of LSPs and SNPs this router originates at the given level, defaulting to 1492 bytes; this object can only be changed while the instance is administratively disabled (replaceOnlyWhileDisabled). An admin raises this (in coordination with isisSysReceiveLSPBufferSize fleet-wide) when a level's LSPs need to carry more information, such as from heavy TE attribute use or large redistributed-route counts, than fit in the 1492-byte default.
