What is prvtIsisSysID?

This is the router's unique 6-byte system ID, normally derived from a MAC address, that gets combined with the configured area addresses to build the router's Network Entity Title. Every IS-IS router in a network must have a distinct system ID or adjacencies and the link-state database will misbehave. Like prvtIsisSysType, it can only be changed while the instance is disabled.
