Description: At which levels is the Intermediate System running? This object follows the replaceOnlyWhileDisabled behavior.

What is isisSysType?

Sets which IS-IS level(s) this router instance runs at: level1IS for an intra-area-only router, level2IS for a backbone-only router, or level1L2IS for a router that does both. Like several other IS-IS configuration objects, this can only be changed while the instance is administratively disabled (replaceOnlyWhileDisabled), so an admin must first set isisSysAdminState to off before changing a router from, say, level1L2IS down to level1IS only.
